Issue Description

I'm unsure if enableSchemaHooks is being enabled when running parse server through published docker container.

my environment variables are as follows:

PARSE_SERVER_DATABASE_OPTIONS: '{"maxPoolSize":10,"compressors":"zlib","useNewUrlParser":true,"useUnifiedTopology":true,"enableSchemaHooks":true}'

when parse server boots up, I get the following in my database options

databaseOptions: {"maxPoolSize":10,"compressors":"zlib","useNewUrlParser":true,"useUnifiedTopology":true}

also attempted to use PARSE_SERVER_DATABASE_ENABLE_SCHEMA_HOOKS: true which was in defintiions.js

module.exports.DatabaseOptions = {
enableSchemaHooks: {
env: 'PARSE_SERVER_DATABASE_ENABLE_SCHEMA_HOOKS',
help:
'Enables database real-time hooks to update single schema cache. Set to true if using multiple Parse Servers instances connected to the same database. Failing to do so will cause a schema change to not propagate to all instances and re-syncing will only happen when the instances restart. To use this feature with MongoDB, a replica set cluster with change stream support is required.',
action: parsers.booleanParser,
default: false,
},
};

Steps to reproduce

docker run parseplatform/parse-server:5.5.3 -e PARSE_SERVER_DATABASE_OPTIONS: '{"maxPoolSize":10,"compressors":"zlib","useNewUrlParser":true,"useUnifiedTopology":true,"enableSchemaHooks":true}'

Actual Outcome

enableSchemaHooks is missing from output of database options, so unsure if it's enabled.

Expected Outcome

enableSchemaHooks shows in database debug options

Environment

5.5.3

Server

• Parse Server version: 5.5.3
• Operating system: ubuntu
• Local or remote host (AWS, Azure, Google Cloud, Heroku, Digital Ocean, etc): local

Database

• System (MongoDB or Postgres): MongoDB
• Database version: 5
• Local or remote host (MongoDB Atlas, mLab, AWS, Azure, Google Cloud, etc): local

Client

• SDK (iOS, Android, JavaScript, PHP, Unity, etc): node
• SDK version: node 16

Logs

Reproduce the reported configuration with the parseplatform/parse-server:5.5.3 Docker command and compare the resulting databaseOptions output. Start with definitions.js and trace how PARSE_SERVER_DATABASE_OPTIONS and PARSE_SERVER_DATABASE_ENABLE_SCHEMA_HOOKS are parsed; done means the documented setting is applied and its behavior or debug output is covered by a regression test.
