…sues older than a month (#7486)

This fixes the following error in the GitHub action:

```
failed to run git: fatal: not a git repository (or any of the parent directories): .git
```

https://github.com/stylelint/stylelint/actions/runs/7609612527/job/20721207993#step:2:19

The failure reason is that the `gh` command tries reading the `.git` repository.
This change provides the repository info through an environment variable supported by `gh`.

The bug's reason is that the `stylelintError`/`stylelintWarning` properties
in a lint result object are not set when `styelint-disable` comment problems are reported.

Also, this change refactors the code around `styelint-disable` comments
to make it more readable and prevent possible bugs.

The new code uses [`Result#warn()`](https://postcss.org/api/#result-warn) in PostCSS for a comment node,
like reporting a normal rule problem.

This fixes the broken benchmark script (`npm run benchmark`)
The error reason is that `rules[ruleName]` has returned a `Promise` since 16.0.0.

```sh-session
$ npm run benchmark-rule -- value-keyword-case lower
...
const rule = ruleFunc(primary, secondary, context);
             ^

TypeError: ruleFunc is not a function
...
```

Also, this changes `parserOptions.ecmaVersion` in the ESLint config to allow top-level `await`.

How to measure:

```shell
npm run -s benchmark-rule -- function-calc-no-unspaced-operator true
```
