fix(tests): ignore gpg signing when running git commit from tests (#5642)

When I run the `tracer` tests locally they try to use my gpg key for
creating dummy git repos. Instead of blocking on user input/signing for
these tests, this change explicitly adds `--no-gpg-sign` to ignore any
gpg signing configured.
