[Bug]: Cannot release opensearch-ruby 3.2.0 because of publishToRubyGems RVM issues

[Earlopain]

Describe the bug

Here's the action being run:

opensearch-build-libraries/vars/publishToRubyGems.groovy

Lines 25 to 35 in 6d35e94

	sh """#!/bin/bash
	gem cert --add ${certPath}
	source /usr/share/opensearch/.rvm/scripts/rvm && rvm use ${rubyVersion} && ruby --version
	cd ${releaseArtifactsDir} && gemNameWithVersion=\$(ls *.gem)
	gem install \$gemNameWithVersion
	gemName=\$(echo \$gemNameWithVersion | sed -E 's/(-[0-9.]+-*[a-z]*.gem\$)//g')
	gem uninstall \$gemName
	gem install \$gemNameWithVersion -P MediumSecurity
	gem uninstall \$gemName
	gem install \$gemNameWithVersion -P HighSecurity
	"""

Notice the absoulte path to RVM. In opensearch-project/opensearch-build@01613af the path where RVM gets installed to got changed, so this invocation doesn't work anymore. If $CONTAINER_USER_HOME is available in this script, that should be used instead.

This issue prevents opensearch-ruby from releasing a new version. Also see opensearch-project/opensearch-build#4624 and opensearch-project/opensearch-ruby#238.

Here is a successful pipeline: https://build.ci.opensearch.org/blue/organizations/jenkins/opensearch-ruby-gems-release/detail/opensearch-ruby-gems-release/29/pipeline/
This one is not able to switch ruby versions because RVM isn't at the expected path: https://build.ci.opensearch.org/blue/organizations/jenkins/opensearch-ruby-gems-release/detail/opensearch-ruby-gems-release/31/pipeline/

To reproduce

ssh into one of the https://github.com/opensearch-project/opensearch-build docker images and try to execute the script from publishToRubyGems without errors.

Expected behavior

publishToRubyGems should be able to switch to available Ruby versions
