wasmer run python/python -- --version should be instant

[Syrus Akbary]

In the alpha1, wasmer run python/python -- --version do a network request always (even though, you previously called in less than 5 mins)

If less than 5 mins have passed since the last check, we should use the cache as we were doing before.

Current:

$ wasmer run python/python -- --version
Downloading python/python@0.2.0
\rPython 3.12.0

Desired:

$ wasmer run python/python -- --version # No network check, extremely fast
\rPython 3.12.0
