EVM Engineering: properly apply test name checks

[smartcontracts]

We have a Go script that checks that test names follow a specific convention that can be found here. The conventions in this script are also described in STYLE_GUIDE.md. However, many tests break this convention because the script was never actually enabled in CI after being introduced. Simply run just lint-forge-tests-check to see this.

We would like to apply this naming convention properly to all tests. We need to follow a multi-step process to achieve this task:

• Update the script to have an exclude list variable that excludes every test file where the check currently fails
• Enable the script in CI as part of contracts-bedrock-checks as well as part of just check inside the justfile
• Clean up the test files over a number of PRs that remove that test file from the exclusion list and fix the test format

Also, let's rename the go script from scripts/checks/names to scripts/checks/test-names since it's more clear.
