[@docusaurus/eslint-plugin] Add plugin setting to recommended eslint config

[lachieh]

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Motivation

In the documentation for the eslint-plugin, the instructions mention that it is a requirement to add the plugin to the project's eslint config before the plugin:@docusaurus/recommended config can be added.

It is pretty standard now to have the recommended configuration add the plugin into the recommended config so that adding the appropriate plugin happens automatically:

• @typescript-eslint/eslint-plugin
• eslint-plugin-prettier
• eslint-plugin-tailwind

I am suggesting that the same change be implemented in this plugin as well. This will allow for easier configuration and better alignment to community patterns.

Self-service

• I'd be willing to do some initial work on this proposal myself.
