Improve naming in the blob spec

[Gozala]

Per storacha/w3up#1342 (comment)

Reading this PR got me wondering if perhaps we should have used memory/allocate and memory/commit instead (which would avoid confusion between service blob and user blob) that way address: BlobAddress would have changed to memory: AllocatedMemory

I think it is worth doing, especially because while discussing federated storage network it came clear that w3up will likely look for a suitable storage node candidate(s) and perform allocation with them. That is to say memory/allocate and memory/commit would make even more sense then. On the other hand space parameter makes very little sense in that context.

Hey @Khwahish29 I'm no longer with the team and not sure what is currently being worked on. I think @travis might be a good person to chat if you're interested in contributing to an ongoing project.

Hi @Khwahish29! Yea unfortunately this isn't super actionable right now - we're probably not going to pursue name changes for abilities until after we transition to UCAN 1.0 at the very least. I'm going to leave this open so we don't lose this suggestion, but may close this after some project gardening in the future.
