[Proposal] Rule to discourage generic link text

[khiga8]

Hello! First off, thank you for this project!

I wanted to suggest an accessibility-focused rule that discourages generic link text from being set such as Read more, Learn more, link, Click here, here, etc.

Screen reader users often navigate through a page by tabbing through links, or by using a screen reader menu that displays all the links on a page. If the link text is super generic like, Learn more, it's not clear where that link will go to without needing to navigate the entire surrounding context. Descriptive link texts are beneficial even for non-screen reader users.

Access Guide: Descriptive link text

I'm thinking that we could have a default array of discouraged link text, and allow additional ones to be configured.

I'm happy to take this work on. Let me know what you think!

This makes sense and should be pretty straightforward since it can use the parser output for links directly. There is precedent in existing rules for analyzing link content that could inform the implementation of this rule. There is already an "accessibility" tag that can be used here. I plan to do a new release soon and will not include this due to timing, but you could iterate in a PR if you'd like. Please see CONTRIBUTING.md or similar PRs for expectations. Thanks!
