check_deps: fix the check for stable NeoGo revisions used in nft-nd-nns

vX.Y.Z-date-commit is very much different from vX.Y.Z and we can have any of
them for NeoGo (vX.Y.Z is even preferable). Previous code ended up this way
for v0.106.3:

++ sed -E -n -e 's/.*neo-go\s.+-.+-(\w+)/\1/ p' examples/nft-nd-nns//go.mod
+ NEO_GO_COMMIT=
+ git merge-base --is-ancestor '' HEAD
fatal: Not a valid object name
+ die 'examples/nft-nd-nns/: neo-go commit  was not found in git'
+ echo 'examples/nft-nd-nns/: neo-go commit  was not found in git'
examples/nft-nd-nns/: neo-go commit  was not found in git
+ exit 1
