Changed default Project Root when build.zig not found

[coffeebe4code]

Zig does not need a project root, but when viewing the std library, there is no build.zig. The current directory is fine for these purposes. zls remains quick on my linux machine.

Addresses this issue

There are linter issues that need fixing:

========================================
Running custom linting rules
========================================
Custom warnings/errors follow:

ale_linters/zig/zls.vim:10 Trailing whitespace
ale_linters/zig/zls.vim:11 Trailing whitespace
./ale_linters/zig/zls.vim:11 Line continuation should match previous indentation
./ale_linters/zig/zls.vim:11 Indentation should be 4 spaces
./ale_linters/zig/zls.vim:13 Indentation should be 4 spaces

The issue with doing this is that ALE will launch an instance of the language server per project root, so you could end up with a lot of duplicate instances being launched. Is there some other project file we can look for to find the root of a Zig project, possibly including the .git directory?

#4993 I'll also mention this idea I pitched. I'll come back to that and finish it eventually in the future if others don't. I would like if if we always used the ale_root` option for setting the root of a project and skipping all filesystem searching so the project root is always configurable, including for the Python project root.

I implemented the suggested change and rebased.

I am going to need to understand how to run these lints myself if I get blocked by the linter again.

@coffeebe4code ALE comes with the custom linter so just enable it in your configuration and ALE will tell you about the linter errors:

linters = {
     vim = { "vint", "ale_custom_linting_rules" },
}

I'll sort this out and get it merged soonish as I have recently become a Zig-Zagger myself. 😃

I'll paste this in every open PR: We finally managed to migrate CI checks for Windows from AppVeyor to GitHub Actions, and we've updated the minimum supported Vim version to 8.2. (Thought Vim 8.0 might happen to work for some.) In order to get checks to run again for a PR you'll need to rebase or merge.
