Extension does not find CodeQL databases using typical Windows paths #3949

Describe the bug
When selecting a CodeQL database to open from a local path, the GitHub.vscode-codeql extension asks the user (via text input pop-up) to provide a path to the local database to be imported, but this only works with forward slashes. Thus, if the user copies a path from their Windows terminal and pastes that path into the text input, the extension will tell the user that the path does not exist. For example C:\ does not exist, but C:/ does.

To reproduce
Start by using Visual Studio Code on Windows. Within the CodeQL extension in Visual Studio Code, select the "Choose Database from Folder" icon from the context menu of the "DATABASES" view. Supply any valid file (or directory) path using backslash (i.e. \) characters and observe the message about the path not existing.

Expected behavior
Expected to be able to find the database path in a Windows terminal, copy that path to clipboard, and paste that path (with back-slashes) when choosing the database folder to open.

Additional context
None
