Deprecate @master

* Use eager Pkg server registry instead of git cloning

This patch removes the git cloning of General and instead uses the eager
registry flavor. In addition, the action exits early if no deps/build.jl
file exist.

* Use env: key instead.

+### Registry flavor preference
+
+This actions defines (and exports for subsequent steps of the workflow) the
+environmental variable `JULIA_PKG_SERVER_REGISTRY_PREFERENCE=eager` unless it
+is already set. If you want another registry flavor (i.e. `conservative`) this
+should be defined in the `env:` section of the relevant workflow or step. See
+[Registry flavors](https://pkgdocs.julialang.org/dev/registries/#Registry-flavors)
+for more information.
