docs: update API endpoint documentation from /v0/ to /v0.1/ (#802)

Update all documentation to reference the stable `/v0.1/` API version
instead of the development `/v0/` version.

Didn't update internal references (e.g. in admin-only docs) as that
probably make sense to keep pointed at v0 as the "dev" option.
