Support old versions

[DelevoXDG]

Currently, setting up the old snfoundry versions fails because of a different snfoundry -V output:
https://github.com/software-mansion/starknet-jvm/actions/runs/6826261535/job/18565799546

Error: Error: unable to determine Starknet Foundry version from 'snforge -V' output: forge 0.6.0

const match = stdout.match(/^snforge ([^ ]+)/);

I think we can modify this to support matching forge <ver> as well, or any x.y.z pattern regardless of prefix.

you can modify it like that maybe:

const match = stdout.match(/(?:^|\s)forge\s+(\d+.\d+.\d+)/);

This modification allows for different prefixes before the version number, such as "snforge" or just "forge". The (?:^|\s) part of the regular expression matches the start of the string or any whitespace character, making it more adaptable to different scenarios. After the match, you can retrieve the version number using match[1]. Make sure to check for null in case of no match to avoid errors.
