ci(github): Run all tests that require external tools in Docker

Use the more fine-granular (than package-level) `RequiresExternalTool`
tag to run all functional tests that require external tools in Docker,
and run complementary functional tests in an isolated environment
created with Flox, similar to unit tests.

Going forward, the plan is to create another Flox environment that only
provides the minimal set of required tools, and run functional tests in
there instead of / in addition to Docker.
