Tighten solana-transaction-context dep version constraint

[billythedummy]

Problem

Current minor version constraint (cargo default) of solana-transaction-context dependency is too loose because v3.1 is incompatible with current mollusk:

error[E0432]: unresolved import `solana_transaction_context::TransactionAccount`
 --> /home/user/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/mollusk-svm-keys-0.7.1/src/accounts.rs:9:70

Solution(?)

Tighten version constraint to patch version.

This is probably just a stopgap measure and the root cause will probably be resolved in the next release with upgraded solana-* deps anyway, so no need to do anything with this PR here, making it mainly for informational purposes

LGTM, but why not update the dependencies directly?

Agreed! We can just go to 3.1 for Agave deps and fix up any broken callsites.
