fix: store bundle hash for ai fix [IDE-380]

[teodora-sandu]

Description

The vulns get returned with AI fixes but the diffs that get generated from the UI when trying to generate an AI fix wouldn't work. This it because of this line of code:

snyk-ls/infrastructure/code/autofix.go

Line 72 in 6de43f0

return unifiedDiffSuggestions, fmt.Errorf("bundle hash not found for baseDir: %s", baseDir)

Added a fix which can be found in the old flow too, where we set the bundle hash on the scanner. Added a test so that next time we change this code we don't forget to set the bundle hash.

To test manually, best to build this version of VSCode: snyk/vscode-extension#467.
