fix:issue related to grom docs

[Ajay9704]

I fixed the broken links in the grails-data/gorm documentation that were reported in issue #14990.
I found several AsciiDoc files that had incorrect relative paths for API documentation links, which would cause link checkers to flag them as broken.

I went through multiple documentation files and updated the links:

In RxGORM docs, I changed ../api/ paths to ../../api/ to fix the relative navigation
In GraphQL docs, I converted {api}/ attributes to proper relative paths like ../../../api/
In Hibernate5 docs, I corrected ../api/ to ../../../api/ to match where docs are generated
I also fixed various API links in the multi-tenancy documentation files

The changes maintain proper AsciiDoc syntax and all documentation builds successfully now.
I tested the .\gradlew grails-doc:docs command and it completes without errors, which means the links should resolve properly when the docs are generated. This should fix the broken links that lychee and other link checkers were reporting.
