fix(help): better align local-additions #38097

Browse Source 
Problem:
Descriptions of plugins often contain taglinks which are generally
concealed. This misaligns them by 2 characters with descriptions that
don't have a taglink in them.

Solution:
Don't count "bar" characters (`|`) for the description width.

Example:

Actual buffer content:
```
myplugin.txt                  |lsp| is cool
myplugin.txt        this is a nice plugin
```

Rendered as:
```
myplugin.txt                  lsp is cool
myplugin.txt        this is a nice plugin
```
