feat: Provide users an alternative link to view x threads

[asbedb]

Description

Introduces a new xCancelGenerator handler that automatically detects Twitter/X links and provides an alternative xcancel.com link. This ensures that community members can view linked content and threads without being forced to log in to an X account.

Summary Features

• Uses Regex to detect only status links from x and twitter -> /https?:\/\/(?:www\.)?(?:x|twitter)\.com\/\w+\/status\/\d+/i.
• Suppresses embed of original link if a match has been detected.
• Returns a converted link using xcancel.com which allows users to read threads without an account.

Tests

Conducted Tests on RTS prior to finalising PR:

PR Summary

• New Feature Development
  A new feature was added to process messages containing Twitter links and convert them into a more user-friendly URL format. This enhancement was realized through a new file named x-cancel-generator.ts.

• Pattern Matching Enhancement
  We introduced a pattern matching technique, here represented as TWITTER_REGEX. Its basic function is to identify Twitter status URLs present in the data effectively.

• Improved Message Processing
  The processing ability of our system has been enhanced by logically ignoring messages from automated sources or bots. Additionally, unnecessary information, known as 'embeds', are now suppressed, contributing to a cleaner user interface. An adequately converted URL is sent to xcancel.com, ensuring the data redirection process is smooth.

• Integration Effort
  Finally, with the update of index.ts, the newly created feature xCancelGenerator is successfully registered within the main list of handlers, consolidating this improvement with existing functionalities. This ensures the new feature works seamlessly with the existing structure.

What about trimming it down further? 👀

Suggested change

	`This \`x.com\` link has been converted to \`xcancel.com\` so that server members won't require an account to view content and threads:\n ${alternativeUrl}`,
	`[Converted to \`xcancel.com\` for members with no X account](${alternativeUrl})`,
