fix(lsp): incorrect rendering of markdown codeblock #40861

Browse Source 
Problem:
LSP hover erroneously drops blank lines before a 4-space-indented
codeblock, which is not valid Markdown. This causes incorrect parsing
and wrong display.

Solution:
Fix `split_lines` so that it doesn't drop the blank line just before
a 4-space-indented codeblock.
