[CI] Skip compile on samples execution

In our check-samples.yml we always compile with Java 25 but we
execute with varying JVMs from 17-25. However, since NullAway is
in main it requires Java 22+. This commit skips the compileJava
target as it should be compiled by previous step that puts it in
local publications repo.
