eslint changes

Only thing left is this:

/builds/project/rules/web/modules/custom/rules/config/schema/rules.context.schema.yml
  25:3  error  Empty mapping values are forbidden  yml/no-empty-mapping-value

And the comments in rules.context.schema.yml mention that the mapping value was deliberately left empty, so I don't want to change that.

However, it would be nice to be able to suppress this one eslint error message in this one location, like we can with cspell:ignore or phpcs:ignore. But I haven't found a way to do that other than turn off eslint (via .eslintignore) for the entire rules.context.schema.yml file, which I don't want to do.

Perhaps instead there's a better way to write the schema if the mapping needs to be extended.

Also, this issue is not meant to solve the bigger JavaScript issue raised in 📌 Update Rules autocomplete.js to track core changes Active .
