axe Linter not respecting tags

Product: axe Linter

Expectation:
when applying the following `axe-linter.yml` config, I would expect that the [html-has-lang](https://dequeuniversity.com/rules/axe/4.4/html-has-lang?application=axe-linter) has been disabled.
```yml
rules:
tags:
- wcag2a
```
adding all other tags (`wcag2aa`, `wcag21a`, `wcag21aa`), doesn't change anything either.
Disabling the rule with
```yml
rules:
html-has-lang: false
tags:
```
works.

Actual:
When having the following `axe-linter.yml` config, the [html-has-lang](https://dequeuniversity.com/rules/axe/4.4/html-has-lang?application=axe-linter) rule should be disabled, since the rule is tagged with `WCAG 2.1`. But it's not :(
```yml
rules:
tags:
- wcag2a
```

Motivation:
I would like to understand how the tags in the config work, or if it is indeed a bug or description issue.
