chore: vendor proper-lockfile dependency

This patch vendors the https://github.com/moxystudio/node-proper-lockfile
project we rely to manage Playwright Registry.

The reason to vender is the following upstream issue that
didn't get resolved in almost a month: moxystudio/node-proper-lockfile#111

Follow-up will apply the fix for the issue to the vendored file.

NOTE: this patch also inlines all code in a single file.
