Debounce reload

[vjpr]

🐛 Bug Report

In core/src/commands/start.ts the reloader is not debounced and triggers reload for simultaenous file changes.

docusaurus/packages/docusaurus/src/commands/start.ts

Lines 102 to 113 in 3166fab

	const fsWatcher = chokidar.watch(pathsToWatch, {
	cwd: siteDir,
	ignoreInitial: true,
	usePolling: !!cliOptions.poll,
	interval: Number.isInteger(cliOptions.poll)
	? (cliOptions.poll as number)
	: undefined,
	});
	['add', 'change', 'unlink', 'addDir', 'unlinkDir'].forEach((event) =>
	fsWatcher.on(event, reload),
	);

This is happening to me when I add a new package as node_modules is being (probably mistakenly) watched somewhere. Still, a simple debounce in chokidar should solve it.

Yes I noticed that already, also happens when you pull from git etc...

We'll add a denounce

(Note you should restart your site on dependency changes)
