Fix Typo in `ResponseCode::PrecoditionFailed`

[Mpinyaz]

Describe the bug

Summary

There is a misspelled enum variant in ResponseCode within the rabbitmq-stream-client Rust crate.

The variant is currently named:

ResponseCode::PrecoditionFailed

This is a typo and should be:

ResponseCode::PreconditionFailed

Although the numeric mapping is correct (RESPONSE_CODE_PRECONDITION_FAILED), the enum variant name itself is incorrect

---

Impact

• Developers must use an incorrect spelling (PrecoditionFailed) when matching response codes.
• Causes confusion when debugging and reading code.
• Mismatched variant name breaks common naming conventions and is inconsistent with AMQP/RabbitMQ terminology.

Proposed Fix

Rename the enum variant and update all match arms accordingly:

- ResponseCode::PrecoditionFailed
+ ResponseCode::PreconditionFailed

And update both the TryFrom<u16> and From<&ResponseCode> implementations:

- RESPONSE_CODE_PRECONDITION_FAILED => Ok(ResponseCode::PrecoditionFailed),
+ RESPONSE_CODE_PRECONDITION_FAILED => Ok(ResponseCode::PreconditionFailed),

- ResponseCode::PrecoditionFailed => RESPONSE_CODE_PRECONDITION_FAILED,
+ ResponseCode::PreconditionFailed => RESPONSE_CODE_PRECONDITION_FAILED,

---

Reproduction steps

1. Create or interact with a RabbitMQ Stream and cause a RESPONSE_CODE_PRECONDITION_FAILED response.
2. Observe how the client maps the numeric code using TryFrom<u16> for ResponseCode.
3. Inspect the resulting enum variant returned by the library.
4. You will see the misspelled variant ResponseCode::PrecoditionFailed instead of the expected ResponseCode::PreconditionFailed.
5. Attempt to match on this variant in your own code.
6. Notice that you must use the misspelled identifier, causing confusing or inconsistent code.

Expected behavior

• The library should expose the correctly spelled enum variant ResponseCode::PreconditionFailed.
• All conversions (TryFrom<u16> and From<&ResponseCode>) should map to and from this correct variant.
• Developers should be able to match errors using the correct and conventional spelling.
• Log outputs and error messages should report PreconditionFailed, not PrecoditionFailed.
