Revert "Merge branch 'feat/issue-433065/Java-XsltTransform' into 'main'"

MR Enhanced sast-rule java/xml/rule-XsltTransform.... (!265 - merged) broke the main branch build, which this MR reverts.

While the MR pipeline was green using Semgrep 1.55.2. Since, upgraded Semgrep to version 1.56.0, which might come with a difference of behaviour causing this error.

Anyway, I'd like to revert this MR to fix the build, before merging it again at a later stage when the root cause of the failure will be understood and fixed.
