Drop the benchmark dependency

[Earlopain]

Motivation

tapioca currently depends on the benchmark gem because of a change to Ruby bundled gems. The functionality is trivial though, and I don't think you have to take on a dependency for that.

Implementation

Just use Process.clock_gettime directly.

Tests

No behaviour change. I just ran some cli commands and they still print the time in seconds. Probably the output is also already asserted against somewhere.

Thanks for the PR. Can you fix typechecking errors?

[Earlopain]

Oops, yeah

[st0012]

We have addressed a few CI issues this week, which should make this PR's build green. Can you rebase the PR? Thx

[st0012]

Based on CI failures, it looks like some dev dependencies Tapioca relies on (identity_cache, rails for example) uses benchmark but doesn't declare it as a dependency (at least not in the released versions Tapioca currently uses).
I think we'd have to wait for them to update their dependencies, cut a release, and bump them in Tapioca, before we can merge this one.

[Earlopain]

How about now?

Load Error is: cannot load such file -- benchmark

Looks like something needs to be fixed on the tests side.

[Earlopain]

Right, some test requires real rails (and activesupport) 7.1.0 which doesn't declare the dependency. I bumped the test to the latest patch release and that should resolve it
