fix: add name field to @stylistic/eslint-plugin configuration

[chadwickellis]

This pull request introduces the implementation of the proposed name field within the @stylistic/eslint-plugin configuration, addressing the feature request for enhanced configuration clarity and simplicity. By integrating a name field, we enable users to directly and intuitively identify and modify the configuration.

Changes Made:

• Added a name field to the configuration objects within @stylistic/eslint-plugin, allowing for straightforward identification.

Benefits:

• Improved Clarity: Directly identifying configurations by name enhances the understandability of the configuration process.
• Reduced Complexity: Eliminates the need to inspect the plugins array, simplifying the configuration adjustment steps.
• Enhanced Developer Experience: Streamlines the process of modifying ESLint rules, making it more accessible and less error-prone.

Examples:
The following code snippet illustrates how a configuration named nuxt:stylistic can now be easily modified:

import { createConfigForNuxt, defineFlatConfigs } from '@nuxt/eslint-config/flat'

export default defineFlatConfigs(
  createConfigForNuxt().then((configs) => {
    return configs.map((config) => {
      return config.name === 'nuxt:stylistic'
        ? {
            ...config,
            rules: {
              ...config.rules,
              // Rule configuration here…
            },
          }
        : config
    })
  }),
)

I look forward to your feedback and any further suggestions for improvement.
