action: fix failed to compile cross v0.2.4

error: failed to compile `cross v0.2.4`, intermediate artifacts can be found at `/tmp/cargo-installG1Scm4`

Caused by:
  package `home v0.5.9` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.68.2
  Try re-running cargo install with `--locked`
