Move lightning-transaction-sync tests to dedicated script
.. and bump its MSRV to 1.75. Recently, `rustls` bumped their MSRV to 1.71. As we depend on them and don't want to continuously pin this security-critical dependency back, we have no choice left but to bump the MSRV for `lightning-transaction-sync` to a version >= 1.71, too. Here, we hence move the `lightning-transaction-sync` tests to a dedicated script and propose to introduce a secondary MSRV of 1.75. We chose this particular version, because: a) it's > 1 year old b) it provides a buffer to 1.71, i.e., if some crate bumped to a version > 1.71, there is a chance we don't immediately have to react again c) it stabilized `async fn`s in traits (see https://blog.rust-lang.org/2023/12/21/async-fn-rpit-in-traits.html), which might become handy for related (BDK) crates, which hopefully will adopt the same target.
