🤖 Generated by Copilot at 5d7aa48

This pull request adds a new code fix for generating XML documentation comments for F# elements that lack them. It defines a new module GenerateXmlDocumentation that implements the logic for the code fix, and registers it with the two types of language servers that FsAutoComplete supports: AdaptiveFSharpLspServer and FSharpLspServer. It also adds tests for the code fix in the test/FsAutoComplete.Tests.Lsp/CodeFixTests/Tests.fs file.

A code fix for F# elements
Autumn leaves of code

WHY

As discussed on discord: This adds a codefix that calls the GenerateXmlDocumentation Command. Contrary to the command, the codefix is only applicable if there is not already xml documentation present.

There are two things the command could be improved on:

• Don't add xml doc lines if there are already some doc lines present.
• Work on all possible AST elements, not just the ones for which we get a result from TryGetSignatureData.

If there is interest in that, I could improve the command in a separate PR.
