Fix allowMultipleJars recommend setting message

[thirtiseven]

Fixes #9897

This PR:

• Make spark.rapids.sql.allowMultipleJars a public config.
• Added a message when case of zero revision numbers on the classpath.
• Do not recommend current config mode in error message.
• Generated doc for this config.

Error message when set it to NEVER:

java.lang.IllegalArgumentException: requirement failed: Multiple rapids-4-spark jars found in the classpath:

Please make sure there is only one rapids-4-spark jar in the classpath. If it is impossible to fix the classpath you can suppress the error by setting spark.rapids.sql.allowMultipleJars to SAME_REVISION or ALWAYS. But setting it to ALWAYS can cause unpredictable behavior as the plugin may pick up the wrong jar.

SAME_REVISION:
