chore: 🔒 use text-based Bun lockfile

Support for the text lockfile format was introduced in version `1.1.40` (https://bun.sh/blog/bun-v1.1.40), it will soon replace the binary lockfile format `.lockb` in the upcoming version `1.2.0`

In addition, cached bun install will become 30% faster thanks to the text-based lockfile format - https://bun.sh/blog/bun-lock-text-lockfile#cached-bun-install-gets-30-faster
