Merge remote-tracking branch origin/master into gsoc-2023-project (…

…#1514)

* Bump maven-failsafe-plugin from 3.1.0 to 3.1.2 (#1502)

* Update Jenkins version to 2.387.3 in pom.xml (#1504)

* Bumps plugin pom from 4.66 to 4.67. (#1506)

https://github.com/jenkinsci/plugin-pom/releases/tag/plugin-4.67 provides
more details of the changes, including:

* Fix hamcrest versioning - @timja
  https://redirect.github.com/jenkinsci/plugin-pom/issues/785

* Update HtmlUnit package for jacoco - @timja
  https://redirect.github.com/jenkinsci/plugin-pom/issues/778

* Use latest plugin BOM for 2.387.x (#1507)

The minimum Jenkins version is already set to 2.387.3 so we should also
update the plugin bill of materials to rely on 2.387.x as well.

* Improve global auth instructions (#1511)

* Simppler phrasing

* Jenkins user API tokens use "Add new Token" now

* Replace outdated issues with more geneeral text

* Remove outdated version support reference (#1510)

Better to not mention a specific version than to mention a specific
version that is many years outdated.
