bircni 96d9f491db fix: strip leading slash from mkdir tarball in CopyTarStream (#1129) ...

`CopyTarStream` creates the destination directory by extracting a one-entry tarball with `DestinationPath: "/"`, but named that entry with the absolute `destPath`. Docker Engine 29.5+ tightened path validation on the copy API and rejects absolute entry names against a `/` destination with `statat var/run/act/actions/<sha>: path escapes from parent`, so the action directory never reached the job container and `actions/checkout` failed during "Set up job". Stripping the leading slash makes the entry relative, matching what the sibling `copyDir` already does and the upstream fix in nektos/act v0.2.89. Adds a regression test asserting the mkdir tarball entry is relative.

 Fixes #1128
