Matrix (#96)

* Update `detsys-ts` for: `Merge pull request #67 from DeterminateSystems/allow-obliterating-id-token-privs` (`4280bc94c9545f31ccf08001cc16f20ccb91b770`)

* Update the defaults / docs on the use-flakehub and use-gha-cache options

* Support the MNC trinary, to allow GHA cache to turn off if FHC is enabled

* let's go?

* arg, you can't parameterize the permissions

* don't fail fast

* Maybe if we bust the token sooner..?

* Clearer job names

* Debug...

* ?

* ...?

* ?

* fancy it up

* more seed

* Test against determinate too

* ...

* derp, obliterate

* Identify the failed-to-setup FHC as not being enabled

* Don't fail on github if the cache is throttled

* derp

* Add a success job for the ci workflow
