ESLint: Add new rules

[t-hamano]

This PR adds three new rules to ESLint that are also introduced in the Gutenberg project.

I believe these rules will improve code quality, prevent unintended problems, and make it easier for contributors.

Rules

@wordpress/dependency-group

Force import statements to add External, WordPress, and Internal as comments to indicate what they depend on.

❌

import CodeMirror from '@uiw/react-codemirror';
import { __, sprintf } from '@wordpress/i18n';
import { fetchThemeJson } from '../resolvers';

✅

/**
 * External dependencies
 */
import CodeMirror from '@uiw/react-codemirror';

/**
 * WordPress dependencies
 */
import { __, sprintf } from '@wordpress/i18n';

/**
 * Internal dependencies
 */
import { fetchThemeJson } from '../resolvers';

@wordpress/i18n-text-domain

Forces the text domain called create-block-theme in the translation function.

❌

__( 'Hello World' )
__( 'Hello World', 'create-block' )

✅

__( 'Hello World', 'create-block-theme' )

react/jsx-boolean-value

Forces the value to be omitted if the value of props is true.

❌

<TextControl
    disabled={ true }
/>

✅

<TextControl
    disabled
/>

Testing Instructions

• Enter a code that does not follow the rules above.
• ESLint should give you a warning.
• If you have the eslint extension installed in your code editor, it will automatically format your code according to these rules.

@mikachan Thanks for the review!

P.S. Since I have been invited as a member of this repository, I would like to merge only the approved PRs myself.
