(chore) rust 1.84 update, dependency updates and workspace deps usage

[gmulhearn]

Updates a bunch of major dep versions (notably askar), updates minor versions in the lockfile with cargo update, and move alot of common dependencies to workspace deps.

Note that #1318 includes some of the same changes for workspace, however this PR adds rust updates and dep updates in addition. As such this PR would close #1318. My bad for not coordinating these PRs better

@JamesKEbert as discussed, i'm now using hyperledger indy-vdr main commit instead of anonyome fork: git = "https://github.com/hyperledger/indy-vdr.git", rev = "b4dc08b"

Awesome stuff! I flagged a number of spots that some dependencies weren't pointing to the workspace, but I wasn't sure if that was intentional or not. 🤷‍♂️
Could you update the README.MD to indicate our higher rust version support?

[gmulhearn]

@JamesKEbert ah yeah I should've explained my method. I was moving deps with more than 1 usage into the workspace. However maybe it's simpler just to move everything. The latter is probs easier to maintain, whatcha think?

[JamesKEbert]

Ah yeah that makes more sense 😆 I lean towards moving them all, as I could definitely see the situation where we add a new dependency to a crate but don't realize it's already present in a different crate. That's obviously not hard to fix, but I don't see a big benefit of not adding them to the workspace file.
Plus that way you know that all dependency versions for any given crate will be in the workspace file, not split between the two files

@JamesKEbert kk agreed. I'll revise tonight

fixed

LGTM -- good stuff :)
