Bunches of dependency updates...

...plus a couple other updates:

* Better document force new
* Add a "triggers" attribute

Minor tweaks; don't ForceNew on registration token change

We'd long promised not to force the destruction/recreation of runner
tokens if the registration token changes.  Now we actually honor that
promise.

_le sigh_

* Use `.env` for tests
* Don't ForceNew on registration_token change
* Not setting RUNNER_REGISTRATION_TOKEN during acceptance tests is now
  fatal

Minor updates

...most behind the scenes.

* use upstream structs for registration
* allow "name" and "maintenance_notes" to be specified

Tests, bugfixes, etc

Reintroduce the gitlabci_runner_config data source

Being able to programmatically construct runner configurations is rather
nifty. (At least, I think so.) The prior way this was implemented was,
shall we say, not sustainable.

Poking around the traefik source one day, I realized I could leverage an
internal tool of theirs to take the, um, modularly awkward
gitlab.com/gitlab-org/gitlab-runner/common and its useful configuration
structs and spew those structs out somewhere we could take advantage of
them. Past that, we can generate other code using the generated code
(insert evil laugh here) to handle the terraform schemas and read
methods necessary.

There's still some improvement to be done (the second-level code
generator is ... um, messy), but I believe it's at a point we can start
taking advantage of it. (Again.)

Internals!

More updates to better talk to terraform.

* Use context-aware resource method variants
* use `tflog` for logging, rather than just `log`

Update the env datasource

Should now reflect the current list of "Predefined environment
variables" correctly.

Fix source address, etc

Largely build/release/docs infrastructure changes, again.

Though we do have an explicit license now, so there's that :)

Sign GitLab release artifacts

Test GitLab releasing

...one, two, three!

No code changes from v0.2.1

Build w/go 1.17 at GitHub

...as the go.mod does kinda insist on it...

Scaffolding, what scaffolding?

This is largely a "bring it all up to dateish" release.

* go to 1.17, plus modules updates
* drop `gitlabci_runner_config` for now (until we figure out how to
  import the runner module w/o explodey)
* include docs, etc necessary for publication on the tf registry
* include GitHub workflow definitions to cause tags to build releases on
  GitHub (mirror-pushed from GitLab)
* other general updates

Really, the only big, user-noticeable thing should be that the config
data-source went away.  Hopefully that won't be for long, though.

v0.1.0; new data sources

Added:

* `gitlabci_runner_config`
* `gitlabci_environment`

Initial release

We build, we work.  Time to actually build/release.
