Can't seem to figure out why the CI is failing, the headings seem correct when I test them.

Closes #2484.

@cherryman in the doc/ale.txt file add one blank line after line 2680, that is after the zls entry you added. After adding the line you can run the test//script/check-toc script directly to see if the error is gone.

@hsanson Thanks, that worked.

I do not Zig or zls but the PR seems ok. It has docs and tests.

Hi, I am unable to get zls working even though I have it installed. I can run it from terminal just fine, but ALE does not recognise it. Here are my linters:

let g:ale_linters = {
    \ 'javascript': ['tsserver'],
    \ 'typescript': ['tsserver'],
    \ 'yaml': ['yamllint'],
    \ 'go': ['gopls'],
    \ 'python': ['flake8'],
    \ 'zig': ['zls'],
    \ }

But if I open a file with extension .zig, here is what ALEInfo shows me:

Available Linters: []
  Enabled Linters: []
  Ignored Linters: []

Edit: had to add this plugin to my init.vim and it worked https://github.com/ziglang/zig.vim Plug 'ziglang/zig.vim'

@Dps910 I suspect that without Plug 'ziglang/zig.vim', filetype wasn't being set to zig as it's supposed to, and so this part of the plugin wasn't being loaded. This is intentional.
