refactor(devtools): remove --config snapshot-build and leave a note for Firefox (angular#55717)

We removed display of the Git SHA in Angular DevTools in angular#55694, so there is no longer a need to stamp release builds in Chrome or Firefox.

I opted to leave a `--config snapshot-build-firefox` option as a no-op which a reader could follow to a comment explaining exactly _why_ we can't stamp Firefox releases. This should hopefully make it less likely that we forget and attempt to re-add this feature in the future only to encounter the same release problems.

+# Angular DevTools for Firefox releases *cannot* be stamped and `--config snapshot-build-firefox` is a no-op.
+# This is because Mozilla requires add-on source code to be uploaded and then they manually reproduce the build.
+# If we stamp the build based on Git information such as the current commit, then reproducing the build would require
+# uploading the entire `.git` directory. We already must upload the entire monorepo, and uploading `.git` as well
+# exceeds the max source file size. To address this, we just *don't* stamp Firefox builds of Angular DevTools.
