MLE-29737: Remove MarkLogic 10 builds from pipeline (remove marklogicVersion=10 lines)

[sumanthravipati]

Summary

Removes all MarkLogic 10 build entries from the Jenkins pipeline. This includes
daily and weekly cron triggers for UBI and UBI-rootless SCAP image builds, the
marklogicVersion==10 conditional branch inside copyRPMs(), and the "10" option
from the marklogicVersion choice parameter.

Root cause

MarkLogic 10 has reached end-of-life and no longer requires automated pipeline builds.

Fix

Deleted 3 cron entries (2 daily, 1 weekly) with marklogicVersion=10, removed the
if (marklogicVersion == "10") branch from copyRPMs(), and updated the choice
parameter from '12\n11\n10' to '12\n11'.

Validation

• grep marklogicVersion=10 Jenkinsfile: 0 matches (PASS)
• make lint: skipped (Docker daemon not available in local environment)

Pull request overview

This PR updates the Jenkins pipeline to stop building MarkLogic Server 10 images now that MarkLogic 10 is end-of-life, keeping automated builds focused on currently supported versions.

Changes:

• Removed the marklogicVersion == "10" handling in copyRPMs() (including the b10/10.0 nightly selection).
• Deleted the nightly/weekly parameterizedCron triggers that ran MarkLogic 10 builds on develop.
• Removed the "10" option from the marklogicVersion choice parameter (now only 12 and 11).
