Dont omit snippet nodes in hover

[ranjithshegde]

Describe the bug
With the new (and incredible) convert_lines_to_markdown option, the hover information for snippet malfunctions.
Many snippets dont have the description key which means the actual snip definition with nodes and code is displayed in help.

With the above option set to true, its all hidden away.

Perhaps it could use a similar parsing function concept as noice.text.markdown.html_entities?

To Reproduce
Steps to reproduce the behavior:

1. Configure noice lsp overrides (set to true)
2. use snippet engine + friendly snippets (just the best test case as it contains verbose snippets with descriptions to undocumented snippets)
3. type any snippet and hover

Expected Behavior

Will be fixed soon :)
