Implement error handling when updating execution state in Bidder

[coderabbitai]

There is a TODO comment in pkg/compute/bidder.go indicating that error handling needs to be implemented when updating the execution state:

// TODO: handle error by either gracefully skipping if the execution is no longer in the created state
//  or by failing the execution

It's important to handle these errors to ensure the system remains robust in case the execution state changes unexpectedly.

This issue was generated based on the discussion in PR #4683: #4683
