Standardize work pool name as Process

[discdiver]

Closes #10842

Updates docs and server instance UI to refer to Process work pool instead of subprocess.

Most places it already was Process (e.g. CLI, type in UI, most docs).

I think it may need to be updated here as well: https://github.com/PrefectHQ/prefect/blob/ae9351fa30a82ecbf06f5c9a8f43b4a5740f41e9/src/prefect/workers/process.py#L145

@desertaxle can you think of anywhere else we might need to update this?

Yeah, the spot you linked is the source of truth that the metadata is derived from, so changing it there will propagate to the collection registry.

Why standardize on "Process" instead of "Local Subprocess"? The latter is more descriptive.

@billpalombi - I hear them referred to much more frequently as a Process worker and Process work pool, so trying to minimize disruption by keeping that naming. Most places it is already referred to as "Process" within Prefect (see screenshots in the issue) - e.g. the type of work pool is "Process", we just display it a few places as Subprocess.

Open to revisiting, but I think it would be felt as a bigger change by users to move to Subprocess.

Thank you @serinamarie and @desertaxle - updated.
