2.6.0 - Upgrade gradle, java17, Tomcat10, project version

I needed a tomcat10 version of this library for an internal project, so I made it.
The only modifications are:

Using jakarta instead of javax

• Changing version configs to update java, gradle and tomcat libs
• Removing hard-coded tomcat version checks
• Adding a "if" statement that fixes an error during the connection
• Changing the package of
  org.bsworks.catalina.authenticator.oidc.tomcat{85/90}.OpenIDConnectAuthenticator
  to
  org.bsworks.catalina.authenticator.oidc.tomcat10.OpenIDConnectAuthenticator
  It just works, at least for me, and I won't maintain it.
