feat: improve tree-sitter highlights for keywords, conditional, repeat, exception

[dhruvmanila]

• keywords
• conditional (if, elif, else,...)
• repeat (for, while, break, continue,...)
• exception (try, finally, catch,...)

Also, these are all already in italic if enabled: https://github.com/sainnhe/gruvbox-material/blob/82c696585d9d7a72596d34a755a6080836ae6561/colors/gruvbox-material.vim#L195-L205

Thanks!

Sorry it's my fault, I merged your PR without thinking carefully.

The syntax highlighting logic used in tree-sitter is different from it's in classic vim syntax. In tree-sitter, the keywords are not italicized, only variables are italicized.

So I reverted your commit.

I don't think that is true or I might be wrong, but I am using italic for the above mentioned groups for a long time. Terminal: kitty OS: macOS Font: JetBrains Mono

You can use custom highlight groups in your vimrc

Yes, actually that's how I am using it:

highlight("TSKeyword", { force = true, link = "RedItalic" })
highlight("TSKeywordFunction", { force = true, link = "RedItalic" })
highlight("TSConditional", { force = true, link = "RedItalic" })
highlight("TSRepeat", { force = true, link = "RedItalic" })
highlight("TSException", { force = true, link = "RedItalic" })

If it's not possible, then no problem. Thanks for taking a look at it :)
