gitlab-ci-local: remove unused dependencies (#397276)

    # Remove intermediate build files for re2 to reduce dependencies.

    #

    # This does not affect the behavior. On npm `re2` does not ship

    # the build directory and downloads a prebuilt version of the

    # `re2.node` binary. This method produces the same result.

    find $NODE_MODULES/re2/build -type f ! -path "*/Release/re2.node" -delete

    strip -x $NODE_MODULES/re2/build/Release/re2.node

    # Remove files that depend on python3

    #

    # The node-gyp package is only used for building re2, so it is

    # not needed at runtime. I did not remove the whole directory

    # because of some dangling links to the node-gyp directory which

    # is not required. It is possible to remove the directory and all

    # the files that link to it, but I figured it was not worth

    # tracking down the files.

    #

    # The re2/vendor directory is used for building the re2.node

    # binary, so it is not needed at runtime.

    rm -rf $NODE_MODULES/{node-gyp/gyp,re2/vendor}
