False positive for at least no-useless-non-capturing-group when required inside new RegExp()

Description

Here https://github.com/adamlui/ai-web-extensions/blob/2e1cc309a53bf59fec003f9290a1a49745be1e6e/utils/bump/js-resources.js#L104:

const reResourceURL = new RegExp(`(?:${rePatterns.cssURL.source})|(?:${rePatterns.jsURL.source})`, 'gm')

... your plugin will falsely warn Unexpected unnecessary non-capturing group. This group can be removed without changing the behaviour of the regex but it's required because the patterns defined earlier are:

const rePatterns = {
...
    cssURL: /^\/\/ @resource.+(https:\/\/assets.+\.css.+)$/gm,
    jsURL: /^\/\/ @require\s+(https:\/\/cdn\.jsdelivr\.net\/gh\/.+$)/gm,
...
}

... so without the grouping (capturing or not) the pipe will compare differently if pre-defined entire patterns weren't wholly grouped already (as in above examples)

I think probably other rules will false positive too since it looks like your plugin doesn't construct new RegExp() before linting to gather the context required for determining truly useless things
