fix: Add describeChromeOnly helper and use to exclude multichain API e2e tests from firefox e2e test runs

[adonesky1]

All of the multichain API tests are currently failing on firefox in CI. This is expected because the Multichain API is not currently supported on firefox. This PR adds a describeChromeOnly helper function to conditionally skip these tests in non-chrome environments

We're going to need a Firefox only version of this at some point. Would it make sense to make this helper accept a browser: Browser arg instead of making it chrome specific here? Then it could be used something like describeOnlyBrowser(Browser.CHROME) describeOnlyBrowser(Browser.FIREFOX)?

Wouldn't we just stop using this describeOnly helper altogether once Multichain is supported on Firefox ?

[jiexi]

Ahh good point. Firefox will have a different entrypoint into the Multichain API, but that'll be handled at the test dapp layer, not the wallet which is what I was originally thinking.

Its possible we'll use different tests for firefox? Probably not though we'd probably switch the transport in the test based on the environment...

I'll just make this change for now since I'm in there fixing the lint issue and will need re-review anyways
