fix(document): avoid triggering setter when initializing Model.prototype.collection to allow defining collection as a schema path name

[vkarpov15]

Fix #13956

Summary

Right now get the following error when you try to use collection as a schema path name:

$ node gh-13956.js 
TypeError: Cannot read properties of undefined (reading 'Symbol(mongoose#Document#scope)')
    at Model.set [as collection] (/home/val/Workspace/MongoDB/mongoose/lib/helpers/document/compile.js:205:32)
    at Function.compile (/home/val/Workspace/MongoDB/mongoose/lib/model.js:4776:30)
    at Mongoose._model (/home/val/Workspace/MongoDB/mongoose/lib/index.js:620:27)
    at Mongoose.model (/home/val/Workspace/MongoDB/mongoose/lib/index.js:579:27)

    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

This PR fixes that, you can now use collection as a schema name, albeit still with the "collection is a reserved schema pathname and may break some functionality." warning.
