Update and consolidate CI build

* Rename env vars for Central credentials.
  This switches from OSSRH to Central Portal Publishing. See:
  - https://central.sonatype.org/pages/ossrh-eol/
  - https://central.sonatype.org/publish/publish-portal-maven/

* Rename master branch to main.

* Fix references to scijava-scripts main branch.

* Consolidate down to a single build.yml workflow.
