ci: Add a workflow to verify the minimum supported Rust version

[andybalaam]

Fixes #3224

Based on the recommendation at https://doc.rust-lang.org/cargo/guide/continuous-integration.html#verifying-rust-version

[andybalaam]

This is failing as expected since the current code requires Rust 1.76. I will merge a PR to update that before this one.

I'd already done #3229 , and I feel like it's marginally better as a separate PR, so...

Well it's more work, now you have to rebase this one onto main.

Did you run cargo update by mistake, or did bumping the minimum version cause a change there? It seems the Cargo.lock has hundreds of lines of changes...

I had to add a dependency, and it changed Cargo.lock. Not sure why...

I undid the Cargo.lock changes and ran cargo check just to make sure, and it did it again so I am fairly sure it wasn't some kind of fat-fingers...

Thanks for checking, and in this case please ignore me :)

(Tiny request if you're so inclined: could we use a workspace dependency for wiremock? Seems it's used in multiple places, and already with different versions 😨 )

I am getting errors in tests / matrix-rust-components-swift:

Undefined symbols for architecture x86_64:
  "_SCDynamicStoreCopyProxies", referenced from:
      __ZN20system_configuration13dynamic_store14SCDynamicStore11get_proxies17h30fbdd908736fcfcE in libmatrix_sdk_ffi.a(system_configuration-6049f0e21ad420f1.system_configuration.97e11328e4c9ed6d-cgu.0.rcgu.o)

Any ideas why?

I will do this in a different PR 👍

Revert the reqwest bump with cargo update -p reqwest --precise 0.11.20.

#3231

[andybalaam]

Just looking for a tick here if someone feels ready to do so.

[bnjbvr]

I'm happy to review, but there's one thing I'd like to try out before 👀

Thanks!
