Hint support

[Marvin-Brouwer]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Problem

I'd like the ability to also display hints using the unified-language-server.

Current solutions

Currently, only info, warning, and, error diagnostics are supported.

Proposed solutions

I suppose changing the node.message() to support this would either require an additional hint boolean or would mean refactoring the fatal field.
Perhaps, it's better to just add a separate node.hint() would keep backwards compatibility.

I'm happy to fork and add a PR with the change, I figured I'd discuss the solution first.
Let me know if you have any questions or if you'd like my help.

unified-language-server translates the VFileMessage severity, determined by the fatal option, into an LSP severity. This project is not the right place to add another severity.

I do have my doubts about adding support for the hint severity though. A pragmatic example would help to move the discussion forward.

Hi! This was closed. Team: If this was fixed, please add phase/solved. Otherwise, please add one of the no/* labels.

Very clear, thanks for your response.
Since you asked for a pragmatic example.

I am currently making a remark plugin with unifiedjs.vscode-remark in mind.

I'm adding some linting rules for required sections, which is good for now. However, I'd really like the ability to have some inline docs on what the section you're typing is means, with some links to guides etc.
I can use the info message for now on the headings I guess but I'd love for it to just be mouse over docs instead of blue squiggles.

Eventually, I would also like to have completion suggestions so I can for example facilitate enums like a set of values allowed in a section, for example document status (draft| proposal | approved). Or maybe even tagging people with autocompletion.

If that's not something you want to support I understand.

@remcohaszing would you be open for me to show you a demo once I have a finished project?
