contracts-bedrock: fix text coloring bug

Github seems to have issues with whatever library they
are using to apply colors to the code for solidity code.
The `'` triggers it to think that it is in a string when
it is not actually in a string because the `'` is wrapped
within two `"`. Just delete the `'` to fix this issue.
The create2 salt is already not completely standard but
it should become standard when we finally have tooling
to easily add a chain to the superchain through the
deploy script, this entrypoint would deploy the proxies
and initialize them to the standard implementations.
