Fix: Make RPC Link Configurable and Other minor fixes

[0xekkila]

• Current interface implementation defaults RPC link for Foundry Script to L1_RPC_URL. This fix should allow RPC url to be easily configurable through validation files.
• Address a Github security issue with eip712sign functions. Even though the interface would be run locally and the exploits may never happen, this fix also contains a fix to follow security measurements.
• Fix an issue where current link in github workflow comment does not work

Instead of having the config file saying the rpc type, it should specify the actual rpc url. The validation tool should only have to read the url from the config file
