Update glob and related packages

[v-osazemeu]

This pull request introduces several updates focused on upgrading dependencies, modernizing tooling, and improving code quality and maintainability. The most significant changes include major dependency upgrades (notably React, Next.js, and FontAwesome), migration to a new ESLint configuration system, and updates to the Node.js version used in CI workflows.

Dependency and Tooling Upgrades:

• Upgraded Node.js version from 18 to 20 in GitHub Actions workflow files (.github/workflows/deploy.yml and .github/workflows/pr.yml). [1] [2]
• Updated multiple dependencies and devDependencies in package.json to their latest major versions, including react, next, @fortawesome packages, typescript, eslint, and more. Added new dependencies such as glob and @tailwindcss/postcss.

Linting Configuration Migration:

• Replaced the .eslintrc.json configuration file with a new eslint.config.mjs file, migrating to the flat config format. This includes updated plugin usage, custom rules, and ignore patterns. [1] [2]
• Updated the lint script in package.json to use the new ESLint command instead of the Next.js lint command.

Build and PostCSS Configuration:

• Updated postcss.config.js to use the new @tailwindcss/postcss plugin instead of tailwindcss.

Minor Code Improvements:

• Made minor type and import cleanups in generate.ts and topics.ts for improved type safety and clarity. [1] [2] [3] [4]

TypeScript has been downgraded from ^5.7.3 to ^5.9.3, which is actually an older version (5.9 < 5.7). This appears to be unintentional. Consider updating to the latest TypeScript 5.7.x version to benefit from the latest features and bug fixes.

Suggested change

	"typescript": "^5.9.3"
