Pulumi ESLint Plugin lacks docs

[jkodroff]

Create a page in the docs under "Languages and SDKs" -> "TypeScript" titles "ESLint Plugin". This page should go after the SDK docs links in the navigation to be consistent with how "Blocking and Async" is laid out for Python.

The page should have roughly the same content as https://github.com/pulumi/eslint-plugin-pulumi/blob/main/README.md, with a few notes:

• Reference https://eslint.org/docs/latest/use/getting-started for instructions on installing configuring ESLint.
• Indicate that the user must install the package @pulumi/eslint-plugin as a dev-only dependency.
• Do not use words like "simply" as they conflict with our style guide.
• We should summarize what the rules cover and refer to the GH repo docs (README.md) for detailed information.
• Note that Linting with Type Information must be enabled.
• Note that the rules must be enabled in the eslint config file.

We should hold off on this until we figure out if we're going to fix pulumi/eslint-plugin-pulumi#41

After getting it working, it's not entirely clear to me whether the ESLint plugin needs to exist at all - I think ESLint itself might now catch the errors the plugin was catching - need to investigate this more as time allows.
