Upgrade snakeyaml to 2.0 in gradle bom

[ilovechai]

Description

Upgrade snakeyaml 1.30 -> 2.0
Seems like dependabot bumped the version in pom.xml https://github.com/odpi/egeria/blob/main/pom.xml#L217 but not in build.gradle

Related Issue(s)

#7509

Testing

gradle open-metadata-implementation:server-chassis:server-chassis-spring:dependencyInsight --configuration compileClassPath --dependency snakeyaml

Task :open-metadata-implementation:server-chassis:server-chassis-spring:dependencyInsight

The snakeyaml update previously caused issues with Spring .
We currently have PRs open to merge a Spring 6 update -- at that time we plan to retry the snakeyaml update.
Hopefully that will be in a matter of days. #7506 or the other PR referenced within
There are also some other updates/reviews of versions to be done once that big change is in.

Let's leave this PR open & hopefully we can get it in soon
