[I] Custom credentials for signing cannot be provided to GCP stores [arrow-rs-object-store]
ilya-zlobintsev opened a new issue, #698:

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**

(This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*)
-->
`GoogleCloudStorage` internally contains two sets of credentials - one used for basic operations, and another for signing URLs. Currently, it is only possible to set the primary credentials in the builder.
I'm using `object_store` with workload identity federation, which is not natively supported by this library: #258. Because of this, I'm not able to generate presigned URLs using my custom credentials.
**Describe the solution you'd like**
<!--
A clear and concise description of what you want to happen.
-->
Expose `signing_credentials` in `GoogleCloudStorageBuilder`. There is already all the wiring internally to support custom credentials, it's just not exposed in the public API.
**Describe alternatives you've considered**
<!--
A clear and concise description of any alternative solutions or features you've considered.

In my specific case, this would not be needed if workload identity federation was supported natively.
