Upgrade to Liquibase 3.10.3

This commit upgrades to Liquibase 3.10.3 and adds an explicit exclude
check as this version started to include a "banner.txt" at the root of
the classpath. Given it may override a banner configured by the user it
is ignored so that the default banner is displayed.

Users impacted by this change can rename their banner and configure the
"spring.banner.location" property to point to it.

Closes gh-23658
