Add ability to add 'tsx?' in test option for eslint rule

[a-menshchikov]

Now there is the only one way to add 'tsx?' test option for eslint rule — by the following code:

.configureLoaderRule('eslint', rule => {
    rule.test = new RegExp(`\\.(${['jsx?', 'tsx?', 'vue'].join('|')})$`)
})

I think it should be an option similar to lintVue.

Closing, as ESLint integration has been removed in #1309 for the next major version of Encore (5).
