Plan v13 Release

[bmish]

Breaking changes:

• Rename recommended config to recommended-legacy, move flat config into exported configs object as recommended, remove string export for flat configs (per Change Request: Standardized export of flat configs to enable programmatic detection eslint/eslint#18095 (comment))
• Update Node support to ^18.18.0 || ^20.9.0 || >=21.1.0" to match ESLint

Previous release:

• v12: https://github.com/ember-cli/eslint-plugin-ember/releases/tag/v12.0.0 (Plan v12 Release #1535)

We'll need eslint v9 support too. Currently I get this error

TypeError: context.getAncestors is not a function
from this line

eslint-plugin-ember/lib/rules/require-return-from-computed.js

Lines 69 to 70 in 7e6bca9

	context
	.getAncestors()

context.getAncestors() is replaced in v9
https://eslint.org/blog/2023/09/preparing-custom-rules-eslint-v9/#context.getancestors()

That's just the one I found, there is potentially other things that need to change for eslint v9

[bmish]

Can you file a separate issue for that? ESLint v9 support can be fixed in a bug fix release.

[Techn1x]

Can do, wasn't sure.

Will jump on that first thing tomorrow
