Steps to Reproduce:

1. Open a project containing devcontainer configuration in (workspaceFolder)/.devcontainer/devcontainer.json.
2. Decide that you don't need the subdirectory, and move the file to (workspaceFolder)/.devcontainer.json.
3. Run the Dev Containers: Rebuild Container command.

Expected Result:

• Container extension uses its usual heuristics to determine the location of the devcontainer configuration in the repo and rebuilds based on the discovered file.

Actual Result:

• Container extension attempts to re-build using the existing config location, which no longer exists, and so errors out (see logs).

Current Workaround:

• Reopen the repo locally.
• Run Dev Containers: Rebuild and Reopen in Container.
• Extension correctly scans for a config file path and builds as expected.
