Release v1.4.1

[muiriswoulfe]

This release includes:

• Transition from using SYSTEM_ACCESSTOKEN to use PR_METRICS_ACCESS_TOKEN for providing authentication. The former will still work but will print a deprecation message. Please update to using PR_METRICS_ACCESS_TOKEN as soon as possible.
• Provision of alternative error messages for GitHub, to provide better guidance as to the fix when insufficient access is provided.
• Correction of minor formatting issues in the GitHub Action readme.
• Correction of the GitHub Action title to avoid having a new name on each publish.
• Updating of dependencies.
