Upgrade to `rust-bitcoin` 0.31.0

[tnull]

Describe the enhancement
rust-bitcoin 0.31.0 was recently released and includes changes that so far kept LDK from upgrading to 0.3X.Y (cf. https://github.com/lightningdevkit/rust-lightning/issues/2124#issuecomment-1791464639).

Additional context Probably currently blocked on https://github.com/rust-bitcoin/rust-miniscript/issues/622

[tnull]

This now seems unblocked as rust-miniscript 11.0 was just released.

@notmandatory Is the current plan to do this as part of 1.0-alpha.3 or 1.0-alpha.4? Trying to wrap my head around when I need for LDK to upgrade to be able to use the latest bdk/rust-esplora-client/rust-electrum-client in LDK Node.

@tnull this PR is still scheduled for the bdk 1.0-alpha.X milestone release. But you are correct we also need to make sure the below PRs are released first:

1. bitcoindevkit/rust-electrum-client#121 released in 0.19.0
2. RCasatta/electrsd#74 released in 0.27.0
3. bitcoindevkit/rust-esplora-client#79 released in 0.7.0
4. bitcoindevkit/rust-hwi#91 released in 0.8.0

Needs to stay in 1.0.0 milestone in order to not block LDK, but we need to check also other dependencies It makes sense to upgrade to rust 0.31.0 for beta (It doesn't seem 0.31 changes are too drastic)

[notmandatory]

take a look at #1191 when this one is done.
