Bug: deprecation(s) in MockInstance causing typescript-eslint to report a no-deprecated error

[jits]

Description of the bug

When migrating from typescript-eslint ^8.3.0 -> ^8.9.0 I started getting the no-deprecated error when using MockInstance.scope().

I reported this on the typescript-eslint repo and they confirm it's expected behaviour, due to the way MockInstance is declared, and declaration merging going on.

An example of the bug

Expected vs actual behavior

Expected: no linting error.

Actual: no-deprecated error when using MockInstance.scope().
