Comment (by talldanwp):

 I've also encountered this after getting a new laptop, but a curious thing
 is that there's no such problem in the Gutenberg project.

 For some background, Gutenberg only uses the `puppeteer-core` package.
 That package doesn't install Chromium when running `npm install`, instead
 chromium is installed when running the test command:

 This is distinct from the `puppeteer` package, which installs chromium
 whenever running `npm install` (which can be a frustrating waste of time).

 My first thought was that perhaps core should also use `puppeteer-core`,
 but then I was surprised to find it already does. It uses the same tooling
 as Gutenberg.

 Looking into the dependencies a bit further, it looks like the issue is
 that the `grunt-contrib-qunit` package has puppeteer as a dependency, and
 an old version at that. This is what's causing the issue. Versions of
 puppeteer are locked to specific chromium versions, so it's likely that
 the version of chromium that project depends on doesn't support the M1.

 IMO, any fix should be made upstream to `grunt-contrib-qunit`, or perhaps
 WordPress should look into an alternative to that project that doesn't
 cause chromium to be installed when running npm install.

 As a workaround you can set the `PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true`
 environment variable, which allows `npm install` to finish, but running
 tests won't work. Technically you should be able to install chromium
 independently (`brew install chromium`) and also set
 `PUPPETEER_EXECUTABLE_PATH`, but I haven't been able to get that working.
