cli: force chrome bin path

[sinedied]

Product: cli

Expectation:
I'm embedding the CLI in another NPM package pre-configured to work out of the box for our needs. In that context, I would like to install a working Chrome / Chromedriver combo to make sure it works on the target machine, so I would like to be able to force chromedriver and chrome binary paths to be used.

Actual: There's currently an option to force chromedriver path, but not to force chrome binary path.

Motivation: Add an option (or environment variable) so we can force the chrome path to be used.

@axe-core/cli: 4.6.0

- Node version: XX  v18.14.2
- Platform:  Mac
