Add a file listing all released, non-removed linter rules (#4990)

Despite personally not fully understanding why,
https://dart-lang.github.io/linter/lints/options/options.html appears to
be a relatively(?) popular resource. Some developer's linter workflows
include copying all rules, then disabling until they're happy. I believe
at least some developers on the Flutter team have done this before.

To still support that workflow and provide a location to redirect to
from https://dart-lang.github.io/linter/lints/options/options.html, this
PR introduces a similar file on dart.dev.

There is a difference though in that it only lists (non-removed) linter
rules that have been released in the latest stable SDK.
