[terraform] Gracefully handle no github environment variables in apply step

[Ben Jones]

We are using the terraform orb to plan and apply our infrastructure, but we aren't needed to have the jobs automatically close PRs in GitHub so we don't have any of the GitHub environment variables set.

terraform/plan is absolutely fine with this, but terraform/apply gives the following error message between the init and plan stages:

Traceback (most recent call last):
  File "/tmp/github.py", line 10, in <module>
    github_username = os.environ['GITHUB_USERNAME']
  File "/usr/lib/python3.7/os.py", line 678, in __getitem__
    raise KeyError(key) from None
KeyError: 'GITHUB_USERNAME'
Unable to update status on PR

The rest of the job still continues, but it would be nice not to have this error message, as it pollutes the output a little.

Orb version: ovotech/terraform@1.6.1
Terraform version: 0.12.17
