Description

Hi all,

There is a dead link the Creating Custom Types section of the SchemaTypes docs.
The "[types]" link points to https://github.com/OpenifyIt/mongoose-types which does not seem to be existing anymore.

mongoose/docs/schematypes.md

Line 688 in 783a5de

[types](https://github.com/OpenifyIt/mongoose-types).

I was not able to find any alternative/up-to-date link to github or similar for this, so not sure what happened with that repo.
Only thing still online is the npm page: https://www.npmjs.com/package/openifyit-mongoose-types

Steps to Reproduce

• Go to Creating Custom Types
• Click on the "[types]" link

Expected Behavior

No response
