💡 RFC: Better error reporting for failed parsing/printing about prettier-plugin-astro

[tonivj5]

Same error happens formating this file (caused by highlighted line): https://github.com/withastro/astro/blob/main/examples/docs/src/layouts/MainLayout.astro#L13

Also, I've found another unexpected behavior with that line:

• if you comment it (using // or /* */) and run formatting, the formater breaks the regex
• Repro:

const { content = {} } = Astro.props;
const currentPage = new URL(Astro.request.url).pathname;
// const currentFile = `src/pages${currentPage.replace(/\/$/, '')}.md`;
const githubEditUrl = CONFIG.GITHUB_EDIT_URL && CONFIG.GITHUB_EDIT_URL + currentFile;

• Run formatting

const { content = {} } = Astro.props;
const currentPage = new URL(Astro.request.url).pathname;
// const currentFile = `src/pages${currentPage.replace(//$/, '')}.md`;
//                                                      ^_ regex has changed! broken, indeed
const githubEditUrl = CONFIG.GITHUB_EDIT_URL && CONFIG.GITHUB_EDIT_URL + currentFile;

• if you uncomment the line, you'll see the code is broken now
