fix: foundry (#2611)

Foundry dropped the specific version of binary we use and it resulted in
this error:
`gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
foundryup: command failed: tar -xzC
/mnt/user-data/jan/tmp/aztec-packages/l1-contracts/.foundry/bin
foundryup: downloading manpages`

I unpinned the version and it fixes it.
