feat(cli/lint): add `--rule` option

[Conaclos]

Summary

Fix #58

This PR adds a new option --rule on the biome lint command. The option allows executing a given rule on a set of files. The configuration is taken into account. Only the severity is overridden to its default, i.e. error for recommended rules and warn for other rules. This ensures that the rule is not off. The rule is executed even if recommended is disabled. However, the rule is not executed if the linter is disabled in the configuration.

To implement this feature, I introduced a new type RuleCode that references a rule with static string slices. This allows passing the rule group/name without cloning it. I modified Rules::matches_diagnostic_code to return static string slices. It acts as a static string interner. I also added methods to set the severity level of a given rule.

The argument of the rule option is passed as parameters in the different calls.

Test Plan

I added tests.

You use the following phrase inside the doc comments, but what does that mean? I believe it requires more explanation. The phrase is too opaque.

The configuration is taken into account.

@Conaclos you forgot to address

taking the configurations file into account

It's still somewhere inside the doc comments and in the description of the PR. Could you please make sure to follow up? I still find that phrase opaque. I truly don't understand what it means 😅

I made the following changes:

Run only the given rule taking the configurations into account

Then I changed to:

Run only the given rule taking the rule options in the configuration file into account

And so:

Run only the given rule or rule group taking the configuration file into account

I am unsure how to address your concern

[ematipico]

What I don't understand is what "taking the configuration file into account" mean. It's very generic. I know you explained that in some comments, it would great to use that explanation here:

The severity of groups and rules configured in the configuration file won't change.
