Add FileSystemSyncAccessHandle

[SimonSiefke]

The FileSystemFileHandle.prototype.createSyncAccessHandle method is used to create and object to synchronously read from and write to a file. It is only available in Web Workers.

MDN Link: https://developer.mozilla.org/en-US/docs/Web/API/FileSystemFileHandle/createSyncAccessHandle

It is already supported by two or more browser engines (Chrome & Safari). Adding the FileSystemSyncAccessHandle api to lib.webworker.d.ts would be a great addition.

Added by #1424 last year. Maybe update your TypeScript version?

That's it. It is supported in TypeScript 5.0.0-beta. Thank you!

Still got error Property 'createSyncAccessHandle' does not exist on type 'FileSystemFileHandle'.ts(2339) on typescript 5.4.5

You need to make sure your worker script is using the right tsconfig; you need to specify "lib": ["webworker", ...]

Problem solved. Thank you!
