fix(templates): Avoid failing if VSCode IDE config is not requested for target and mapper cookiecutter templates

[ReubenFrankel]

Related to #2182 and #2183

These templates currently do not have a .vscode directory, and so when VSCode IDE config is not requested (i.e. 2 - None option) the post generate project hook fails trying to remove a directory that doesn't exist:

FileNotFoundError: [Errno 2] No such file or directory: '.vscode'
ERROR: Stopping generation because post_gen_project hook script didn't exit successfully

This PR simply ignores that error for target and mapper templates, should it occur. I haven't added any VSCode config (e.g. launch.json) as it's probably not gonna be the same as the tap template (in hindsight, I might have been a bit quick to exclude launch.json from the check-json pre-commit hook).
