[eslint-plugin] Flag Popover as deprecated in favor of PopoverNext

[ggdouglas]

Summary

Adds Popover to the no-deprecated-core-components and no-deprecated-components ESLint rules, suggesting migration to PopoverNext. This complements the JSDoc @deprecated annotation added in #8006.

The mapping uses the same-package string format since both components live in @blueprintjs/core. Test cases cover named imports and namespace imports.
