The value of this variable is evaluated when the 'filetype' option is
changed and should be a command string that will undo any configuration
changes that the plugin has made.

Problem:
Checking if the tag is nvim-owned (defined in a $VIMRUNTIME/doc/*.txt
file) is too expensive for now without non-obvious workarounds
Solution:
Only set url extmarks for $VIMRUNTIME/doc/*.txt files.
Closes: #36163
fix(help): only set url for nvim-owned tags
Problem:
1. gx on |nonexistingtag| opens
https://neovim.io/doc/user/helptag.html?nonexistingtag.
2. b:undo_ftplugin doesn't remove url extmarks.
Solution:
1. Check if the tag is defined in a help file in $VIMRUNTIME.
2. Solution: clear namespace for buffer in b:undo_ftplugin.
Problem: filetype: KerML and SysML files are not recognized
Solution: Detect *.kerml as kerml filetype, detect *.sysml as sysml
filetype, include a kerml and sysml filetype plugin

Problem: filetype: Not all PKL files are recognized
Solution: Detect *.pcf as pkl filetype, detect using the pkl-lsp://
protocol as pkl filetype, include PKL syntax script
(Jan Claußen)
This adds basic syntax support for the new PKL language by Apple.
What works:
- Shebang support
- Comment support
- Integers (decimal, hex, octal and binary) support
- Floating point support including exponentials
- Basic datatype support
- Unicode escape delimiters
- Escape code support
- String interpolation
- Support up to five pounds for custom delimiters
- Folding of multi-line comments and blocks
What doesn't work:
The language heavily uses parameterized type declarations, which can get
very complex. It is very hard to highlight this properly. There is
official Tree-sitter support for this. Since it is hard to pull this off
in a vim syntax file, I opted for basic support of the data types.

Problem:
`gx` does not work on tags in help buffers to open the documentation of that tag in the browser.
Solution:
Get the `optionlink`, `taglink` and `tag` TS nodes and set extmark "url" property.
`gx` then discovers the extmark "url" and opens it.
Filetype plugins should not assume they are the only file to execute on
behalf of a buffer's filetype: other filetypes may use them, and
dotted filetypes may cause multiple to run. When this occurs, they
should _build_ on their respective b:undo_ftplugin settings, not
overwrite each other.
For example, when using a dotted filetype wiki.markdown, the wiki
filetype plugins go first. Then, during the markdown filetype plugins,
the HTML plugin's unconditional assignment to b:undo_ftplugin trashes
any data previously stored there by the wiki filetype.
Follow the pattern elsewhere of assigning or appending conditionally.

Problem: Vim's help file doesn't have any syntax for comments, but
'comments' and 'commentstring' are still set in the help
buffer.
Solution: Unset 'comments' and 'cms' in help buffer

Problem: :term splits new window above in vim, but in nvim it change
the buffer for current window
Solution: :hor term to ensure consistent splitting for Vim and Neovim

Problem: Health check floating window gets closed when pressing 'gO' to show TOC because LSP floating preview system auto-closes on BufEnter events triggered by :lopen.
Solution: Temporarily disable BufEnter event for the current window during TOC operations and adjust window layout to prevent overlap.
last `unmap` can cause the error "E31: No such mapping" when
`doaudocmd FileType go` if appending other commands to `b:undo_ftplugin` i.e.
the space and the next bar as `let b:undo_ftplugin .= ' | setl ...'`.
