types: make property names show up in intellisense for UpdateQuery

[vkarpov15]

Fix #14090

Summary

I took a look, and with this changes it looks like intellisense picks up property names as well as update operators

Examples

@vkarpov15 I think this change cast types to any. But this one gives the complete typing, even inside the objects:
index.d.ts

type _UpdateQuery<TSchema, AdditionalProperties = AnyObject> = TSchema | {

Maybe using something like NestedPartial on TSchema:

type _UpdateQuery<TSchema, AdditionalProperties = AnyObject> = Partial<TSchema> | {

[vkarpov15]

This doesn't change the cast type at all, you still end up with AnyObject at the end; just helps with intellisense. I'm open to alternatives, and Partial<TSchema> | AnyObject may be better in some cases, but the approach in this PR is likely the minimum viable change and I don't see any reason why Partial<TSchema> | AnyObject would be better.

I thought, this issue is complaining about the types:
#14090 (comment)

What you said is true, the only way is to replace AnyObject(which i guess breaks some stuff).

should this fix maybe be targeted at 7.x too?

@hasezoey yeah I'll cherry pick
