Description

Closes #671

This workflow ensures that every pull request description includes an associated issue number for better tracking and clarity. If the required format is not met, contributors will receive clear feedback on how to correct it.

Error Case

When the PR description does not meet the required format (missing the issue reference):

• PR description: Fixed bug
• Output:
  The PR description should include the issue number assigned to you. ⚠️
  ##[error]An issue reference like 'Fixed #' must be included in the description.

Success

• PR description: Fixed # or Issue number # or Closes #
• Output:
  PR description is valid.
  All checks passed.
