feat(eslint-plugin): add support for valid number and bigint intersections in restrict-plus-operands rule

[leonsilicon]

PR Checklist

• Addresses an existing issue: extends [restrict-plus-operands] false positive on types like {} & string #2506
• That issue was marked as accepting prs
• Steps in CONTRIBUTING.md were taken

Overview

This PR extends the functionality of #2628 to also support number intersections and bigint intersections. A real-world use case for this functionality would be the new reactivityTransfrom Vue macros: vuejs/eslint-plugin-vue#1839

(also the code was mainly copied from PR #2628 and tweaked for numbers and bigints)

This change seems reasonable, but doesn't address an existing open issue. Could you please file one and fill out the template there that asks for more information?

We generally ask that all PRs resolve an (open) issue because it raises visibility to the community and gives folks a chance to discuss.

Excellent, thanks @leonzalion! 💯
