bb8f833ca0 Update instruction.rs (kilavvy)
0ce622e668 Update message.rs (kilavvy)
f61941bbe6 Update serialized_signature.rs (kilavvy)
1d2de62e01 Update mod.rs (kilavvy)

Pull request description:

  This PR fixes several typos in comments across multiple files:

  - Fixed typo `interpretted` -> `interpreted` in `blockdata/script/instruction.rs`
  - Fixed typo `neccessity` -> `necessity` in `p2p/message.rs`
  - Fixed typo `underlflow` -> `underflow` in `taproot/serialized_signature.rs`
  - Fixed typo `ambigous` -> `ambiguous"` in `units/src/amount/mod.rs`

  These changes only affect comments and documentation, no functional code changes.
