fix(js-client): fallback to space.version for cache version

[intellix]

The way that new versions are discovered today, is that it checks for data.cv and saves it in-memory. The problem is, the only way that data.cv is available, is through heavily cached endpoints. The cdn/spaces/me endpoint is only cached for 2 seconds and has a small response and includes the latest known version, but it's not used at all, until this PR.

With this change it'll allow me to poll the cdn/spaces/me endpoint every 60 seconds and switch back to querying for published content using the SDK.

Addressed the findings from this comment: #105 (comment)

pnpm patch for anyone that needs this now (me, but sharing anyway):

for 4.4.4:
