oauth2 gem used by fhir_client is EOL

[thomasdziedzic-calmwave]

When installing fhir_client I get this EOL message for oauth2:

Post-install message from oauth2:

You have installed oauth2 version 1.4.11, which is EOL.
No further support is anticipated for the 1.4.x series.

OAuth2 version 2 is released.
There are BREAKING changes, but most will not encounter them, and upgrading should be easy!

We have made two other major migrations:
1. master branch renamed to main
2. Github has been replaced with Gitlab

Please see:

• https://gitlab.com/oauth-xx/oauth2/-/blob/main/CHANGELOG.md
• https://groups.google.com/g/oauth-ruby/c/QA_dtrXWXaE

Please upgrade, report issues, and support the project! Thanks, |7eter l-|. l3oling
