feat: Add versioned tx support in rust client

[cryptopapi997]

Currently, there's no way to build versioned txs using the anchor rust client, only legacy transactions are possible. This PR changes that by introducing the same transaction-related method with a _versioned suffix & deprecates the old methods. This is relevant in that it allows for switching between V0 and legacy transactions with the same code (and the upcoming V1 format).

@cryptopapi997 is attempting to deploy a commit to the Solana Foundation Team on Vercel.

A member of the Team first needs to authorize it.

I don't think deprecating here necessarily makes sense; the vast majority of use cases are going to be using legacy so it adds boilerplate to the common case. I think we can just use the docstring to point at the versioned method

My thinking was to have a singular way to build & send transactions, however I see the value in keeping the base case as simple as possible also, so fine by me. Removed the deprecation & switched to just mentioning it in the comment

addressed the review, lmk if this works @jamie-osec . I had a look at the CI failures, but those seem to be unrelated since they're all something related to something onchain invoked via the ts client (neither of which this PR modifies)

Changes LGTM, will rerun CI

Can you fix the new conflict?
