fix(linter): move eslint-config-prettier to the end for proper override (#28503)

There is a conflict between ESLint and Prettier rules, which causes
incorrect formatting behavior.

Reordering the config so that `eslint-config-prettier` is applied last
ensures proper rule overrides and resolves conflicts with Prettier.
