Toolchain selection quick pick does not update UI after selection

[jcubit]

Describe the bug
The toolchain selection quick pick is not updated after selecting a swiftly toolchain

To Reproduce
Steps to reproduce the behavior:

1. Install a few different toolchains via Swiftly.
2. Run the Swift: Select Toolchain... command.
3. Select a swiftly toolchain which is not in use
4. Add vscode workspace configuration,
5. Reload extensions with the vscode prompt

You'll notice that when you open again the toolchain picker the selected toolchain was not updated and is showing the old toolchain in use.

Expected behavior
The next time that I run the "Swift: Select Toolchain... command" I expect to see the previously selected toolchain to be "in use" in the UI.

Environment

• OS: macOS
• Swift version (output of swift --version)
  Apple Swift version 6.2.3 (swift-6.2.3-RELEASE)
  Target: arm64-apple-macosx15.0
  Build config: +assertions

I'm only able to reproduce this with swiftly v1.0.1. Upgrading to swiftly v1.1.1 should resolve this for those looking for a workaround.

Indeed, updating to swiftly v1.1.1 works for me as well
