chore: remove bson from devDependencies

[rtritto]

Remove bson from devDependencies.

Note: version 4 of bson in peerDependencies is updated from 4.2.3 to 4.6.3 (source)

[rtritto]

To consider:

ejson-shell-parser/.github/dependabot.yml

Lines 17 to 20 in c42e0bf

	# Ignore any upgrades to BSON as this requires a new release
	- dependency-name: 'bson'
	# Only imported for that performance comparison
	- dependency-name: 'mongodb-query-parser'

Same case for mongodb-query-parser.

At least we should update version of bson in peerDependencies (from 4.2.3 to 4.6.3) for reason of #109 (comment)

I can create another PR for this.
