MINOR: Bump version of grgit to 4.1.1 (#11561)

grgit 4.1.0 caused unsupported version error during gradle builds.
The reason was that grgit 4.1.0 uses always the latest JGit version
internally. Unfortunately, the latest JGit version was compiled with
a Java version later than Java 8 which caused the unsupported version
error during gradle builds for Java 8.

grgit 4.1.1 fixed this issue by upper bounding the version of JGrit
to a version that is still compiled with Java 8. Consequently, we can
remove the hotfix we merged in commit d1e0d2b474
and instead bump the grgit version from 4.1.0 to 4.1.1.
