feat(js): Update web worker guide with new webWorkerIntegration APIs

[Lms24]

DESCRIBE YOUR PR

closes getsentry/sentry-javascript#16977
closes getsentry/sentry-javascript#16974

This PR adds documentation for two new WebWorker-related APIs:

• Sentry.webWorkerIntegration()
• Sentry.registerWebWorker()

More details in getsentry/sentry-javascript#16981

I also gave the entire web worker guide a facelift, removed some unnecessary notSupported platforms and added an integration page for the new integration. Also, the guide now includes a paragraph about configuring Vite correctly for worker builds which was raised in getsentry/sentry-javascript-bundler-plugins#755.

LEGAL BOILERPLATE

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Bug: Incorrect Plugin Configuration Causes Runtime Error

The worker.plugins configuration incorrectly uses the spread operator (...sentryPlugin) on sentryPlugin, which is a single, non-iterable plugin object. This will cause a runtime error. The correct usage is [sentryPlugin].

docs/platforms/javascript/common/best-practices/web-workers.mdx#L175-L176

sentry-docs/docs/platforms/javascript/common/best-practices/web-workers.mdx

Lines 175 to 176 in ccbd7a1

	// Vite plugin for worker bundle
	plugins: () => [...sentryPlugin],
