Two CI validation errors have been fixed:
* A duplcate entry has been removed from the lockfile
* `@metamask/phishing-warning` has been added to the depcheck config,
so that it knows that dependency is being used (in e2e tests)
* Create `.zip` files deterministically
Our build system now creates `.zip` archives deterministically.
Previously the `.zip` file would differ between builds even when the
files being archived were identical. This was because the order the
files were passed in was non-deterministic, and the `mtime` for each
file was different between builds.
The files are now sorted before being zipped, and the `mtime` for each
file has been set to the unix epoch.
* Update lavamoat build policy
An externally hosted phishing warning page is now used rather than the
built-in phishing warning page.The phishing page warning URL is set via
configuration file or environment variable. The default URL is either
the expected production URL or `http://localhost:9999/` for e2e testing
environments.
The new external phishing page includes a design change when it is
loaded within an iframe. In that case it now shows a condensed message,
and prompts the user to open the full warning page in a new tab to see
more details or bypass the warning. This is to prevent a clickjacking
attack from safelisting a site without user consent.
The new external phishing page also includes a simple caching service
worker to ensure it continues to work offline (or if our hosting goes
offline), as long as the user has successfully loaded the page at least
once. We also load the page temporarily during the extension startup
process to trigger the service worker installation.
The old phishing page and all related lines have been removed. The
property `web_accessible_resources` has also been removed from the
manifest. The only entry apart from the phishing page was `inpage.js`,
and we don't need that to be web accessible anymore because we inject
the script inline into each page rather than loading the file directly.
New e2e tests have been added to cover more phishing warning page
functionality, including the "safelist" action and the "iframe" case.
* Create `.zip` files deterministically

The files are now sorted before being zipped, and the `mtime` for each
file has been set to the unix epoch.
* Update lavamoat build policy
The lockfile would change upon install due to a redundant entry. This
seems to have been introduced in #14612 as a result of running
`yarn-deduplicate`.
