Spaces in certain env vars will break bolt invocations

[donoghuc]

Describe the Bug

Spaces in some environment variables overrriden in bolt's wrapper script cause bolt invocations to fail.

Expected Behavior

If my gem env vars are messed up, bolt should still be able to run.

Steps to Reproduce

[root@biggest-cherry ~]# GEM_PATH='/something/ with/ a /space' bolt command run whoami -t localhost
env: with/: No such file or directory

Suggested Fix

Escape the env vars in https://github.com/puppetlabs/bolt-vanagon/blob/main/resources/files/posix/bolt_env_wrapper#L15-L21 (for example BOLT_ORIG_GEM_PATH="$GEM_PATH"
