Default support of any error code

[Polo2]

Following #465,

We noticed that, if Bump.sh API returned a new HTTP error code (for example 402), currently it's necessary
to add specific code to support this 402 status error, available only with a release of the CLI.

It could be nice to add a default treatment of any HTTP error code, to make sure any error from Bump.sh API is 'understood' by CLI, and that provided error message (with JSON) is displayed.

That's the whole point of the 400 HTTP code and this (already handled) error treatment in the CLI.
