chore: replace deprecated jest.autoRun in .vscode/settings.json

[devjiwonchoi]

Why?

Since jest.autoRun in .vscode/settings.json is deprecated, this PR replaces it with an equivalent setting using the recommended migration guide.

Starting from v6.1.0, if no runMode is defined in settings.json, the extension will automatically generate one using legacy settings (autoRun, showCoverageOnLoad). To migrate, simply use the "Jest: Save Current RunMode" command from the command palette to update the setting, then remove the deprecated settings.
