gvm cd fails with Unrecognized command line argument: ''

[stackbaek]

When .go-version file contains go version without go (e.g. 1.22, instead of go1.22), cd-ing into this directory prints error

Unrecognized command line argument: ''

We should consider allowing version without the prefix go in the regex

gvm/scripts/env/cd

Line 184 in dd65253

local regex='^(go([0-9]+(\.[0-9]+)*))$'

same error here, pls consider adding an ignore rule to workaround .go-version file not in expected format
