ci: Build monorepo on op-node change

This reverts commit 54f7dcf1.

Co-Authored-By: @mds1

Fixes an issue where the pnpm-monorepo job would not build due to `check-changed`, but downstream jobs like `contracts-bedrock-test` would. This causes the contracts to be rebuilt on the downstream jobs and causes OOMs and spurious test flakes.

contracts-bedrock: cleanup expect emits

ctb: silence compiler warning

Make a function `pure` rather than `view` to silence a compiler warning.
This likely appeared after updating the version of `forge-std`.
The function that was updated wrapped the `bound` function so its likely
that the `bound` function was updated to be `pure` when it used to be
`view`.

Modern foundry added the ability to `vm.expectEmit(address)`. This is an
alias for `vm.expectEmit(bool,bool,bool,bool,address)` where each of the
booleans are true. It is important to include the address of the
contract this is expecting to emit the event. If all of the bools are
going to be true, might as well use the short hand to simplify the
source code as well as the bytecode.
