chore(rate-limiter): bump 0.0.6 -> 0.0.7 for connection-timeout release

Companion bump to the connection-acquisition timeout fix on this
branch.  0.0.6 was the TLS-support release (cpex-plugins#74); 0.0.7
ships the timeout fix on top of it.

No behavioural change in this commit on its own — version bump only.
Cargo.lock regenerated via ``cargo update -p rate_limiter``.
