[EngSys] update dataplane.code-workspace

[jeremymeng]

to only include folders that are mostly maintained by the central JS SDK team.
To have all SDKs available in VS Code, open the repository directory instead.

The tssdk path is fixed as core-http has been removed.

Also add "streetsidesoftware.code-spell-checker" to VS Code recommended extensions

Not sure whether other SDK authors are also using this workspace. We could also rename or have a separate core workspace?

Pull request overview

This PR streamlines the dataplane.code-workspace configuration to focus on packages maintained by the central JS SDK team. The workspace is reduced from ~50 folders to ~30 folders, removing non-core packages like service-specific SDKs (e.g., communication, storage, cosmos). The PR also fixes an outdated TypeScript SDK path reference and adds the code spell checker extension to the recommended extensions list.

Key Changes

• Removed service-specific SDK folders (communication, storage, synapse, etc.) to focus on core infrastructure packages
• Fixed the typescript.tsdk path from the removed core-http to sdk/core/core-rest-pipeline
• Added trailing commas throughout the JSON for better git diffs and consistency

TBH I haven't used the workspaces in some time as VS Code became fast enough at opening the root of the repo and we don't have the root package.json poisoning things anymore

Yeah I always open the root directory. Maybe this file can be deleted then.
