chore(rust): update reqwest to 0.12

[baszalmstra]

This patchs bumps the reqwest version used by the Rust SDK from 0.11 to 0.12. It basically takes the commit from #345 . I do not know why that was deleted..

Related Issue or Design Document

Reqwest 0.12 has been out for 2 months. It would be nice to share the same reqwest Client with multiple crates but a lot of crates update to reqwest 0.12. This makes the reqwest Client incompatible with the version used in the Ory SDK.
