Add Slint

Description

Add the Slint language

Checklist:

• I am adding a new language.

  • The extension of the new language is used in hundreds of repositories on GitHub.com.

    • Search results for each extension:
      • https://github.com/search?q=path%3A*.slint+-is%3Afork+-repo%3Aslint-ui%2Fslint&type=code

  • I have included a real-world usage sample for all extensions added in this PR:

    • Sample source(s):
      • Coming from the examples in https://github.com/slint-ui/slint
    • Sample license(s): MIT

  • I have included a syntax highlighting grammar: https://github.com/slint-ui/slint-tmLanguage

  • I have added a color

    • Hex value: #2379F4
    • Rationale: Color mentioned there: https://github.com/slint-ui/slint/tree/master/logo#color

  • I have updated the heuristics to distinguish my language from others using the same extension.

    • I don't think there are other languages with the same extension

Two of your samples are too big as they're being suppressed by the diff by default. Please replace these with smaller samples.

You need to also add the cached license .yml file that would have been created when you ran script/add-grammar to add the grammar.

I edited them to removed big parts so they are small enough.

Added.

I had forgotten to git add this file. I tried to clean everything and re-create it and that didn't work at first. Now this should be the correct one.

Whoops! There's only one file change now.

Sorry about that.
I'm doing this in codespaces which I'm not familiar with. Should be alright now.

All looks good now.
