feat: add missing disableErrors to globals findOne operation

[rilrom]

What?

This PR introduces the disableErrors option into the global findOne operation.

Why?

disableErrors is handy for certain flows where a user may be unauthorised but you don't need an error to be thrown, instead you would prefer an empty result.

Without this, the developer needs to catch the error themselves, leading to inconsistencies as some operations have disableErrors and others do not.

How?

Introduced the disableErrors option to the global findOne operation.

Additional information

• Initial discord discussion.
• A PR was created to address this in mid 2024 but was later closed.
• There is opportunity here to include disableErrors in a number of operations that seem to be lacking it, especially in the sdk package. Originally I included these changes in this PR but have since removed to instead allow for some discussion before we consider introducing them in a separate PR.
• There is opportunity to introduce better test coverage in a separate PR for disableErrors across existing operations that use it.
• In packages/payload/src/collections/operations/restoreVersion.ts, disableErrors exists in the types but is not actually implemented. I have left this as is for now but wanted to flag it.
