Fix Prettier violations: add missing semicolon and trailing commas in flat config.
These style errors will fail linting. Add the semicolon after the return and commas where indicated.

In eslint-plugin-prettier.js around lines 143 to 154, the flat/recommended
config is missing a semicolon after the getter's return and missing trailing
commas in the object literals; fix by adding a semicolon after "return
eslintPluginPrettier;" inside the getter, and add the necessary trailing commas
after the plugins getter block, after the rules object entries (and after the
flat/recommended object entry) so the file conforms to Prettier rules.

150-154: Confirm parity with classic “recommended” (extends 'prettier').The non-flat
recommendedextendsprettier(eslint-config-prettier), but the flat variant doesn’t import/merge those disables. If divergence is intentional, fine—just make sure it’s documented; if not, consider bundling equivalent disables or advising users to include the flat config from eslint-config-prettier alongside this.
144-144: Nit: clarify the displayed config name.Consider renaming to
prettier/flat/recommendedfor clearer debugging output in Flat Config stacks.

File: test/prettier.mjs:28-35
Timestamp: 2025-06-17T07:50:43.759Z
Learning: In the eslint-plugin-prettier test file, the pattern `const ESLint = eslintUnsupportedApi.FlatESLint ?? eslint.ESLint;` works correctly even though `eslint` is declared later with `var eslint;` because the hoisted declaration makes `eslint` available throughout the file, and `eslintUnsupportedApi.FlatESLint` is always truthy when this code executes, so the `eslint.ESLint` fallback is never evaluated.

146-149: Getter pattern is correct for self-referencing the plugin.The lazy getter cleanly avoids TDZ/self-reference issues and keeps the flat config consumable without early binding. This matches our prior learning from PR #743 about deferring resolution safely.

Flat config is already supported per https://github.com/prettier/eslint-plugin-prettier?tab=readme-ov-file#configuration-new-eslintconfigjs I don't want to add two ways of doing the same thing. |
The form that was added does not follow the conventional pattern followed by the rest of the other libs. I think it would make a lot of sense to follow the same pattern. |

Adds simplicity when importing eslint configurations into new eslint configuration.
