Finalize the maven central publish process for ecocode-rules-specifications

[dedece35]

Create / update documentation for the process "how to publish a new version of ecocode-rules-specifications to maven central " :

• launch the manuel workflow "Publish package to Maven Central Repository" (Actions tab) on desired tag
• because of no automatic publishing process (only now because of internal choice to first validate staging published version before public publish) :
  • go to Nexus "https://s01.oss.sonatype.org/#welcome" and login with personal account or generic one
  • go to "staging repository" tab, next check if new version publish is here
  • a new staging URL is avalaible to check it in one project
  • if ok, click on "deploy" to publish it on public maven central
  • => we can make this process automatic with changing a flag on pom.xml file

Currently, issue created because we cant login on Nexus Platfrom (but ok on JIRA plateform) : https://issues.sonatype.org/browse/OSSRH-97889
Once JIRA resolved and login ok with generic account, do following tasks to use new tokens (instead of @jycr personal tokens) :

• clic on "profile"
• go to "user token", next generate new
• change values in github settings / secrets / actions for keys OSSRH_TOKEN (new password) and OSSRH_USERNAME (new login)
• check all is OK : create a new release, launch publish workflow, deploy new version of artifact on Nexus UI

update :

• JIRA https://issues.sonatype.org/browse/OSSRH-97889 resolved by Sonatype team
• upgrade of token with generic ecoCode account
• test publishing new version of ecocode-rules-specification on maven central OK with 1.4.5 version

update 2 :

• upgrade pom.xml to enable automatic release
• make a new release 1.4.6
• launch workflow "publish to maven central" (Action tab) to check automatic publish on Maven central

All is OK.
Big thanks @jycr for help !
