Fix report header regex for shorter contract names

[Kebiled]

Description

reportHeaderRegex was set up to only allow for one space between the contract and the ending pipe char |.

On some contracts with shorter names, and longer method names, there will be more than one space in the forge tests tables formatting.

Example output from my forge test:

| src/Shop.sol:Shop contract     |

This will cause the action to ignore these tables when gathering info from the reports.

I've changed the regex to allow for any number of whitespace characters after contract with /^\| .+:.+ contract +\|/

Thanks a lot for your contribution, releasing a new patch version for this specifically!

I simply need you to pull main and update this PR by running yarn && yarn release again (I bumped the action's dependencies because they weren't for a long time)

Or I'll merge the changes myself but having you as a contributor of this repository is good!

Thanks! Will get that done tomorrow

@Rubilmax FYI, sorted issue
