Fix incorrect DS_EXCLUDED_PATHS test for js-npm

What does this MR do?

This MR fixes an incorrect test for js-npm/minified-jquery with the DS_EXCLUDED_PATHS variable by doing the following:

• Moving qa/expect/js-npm/minified-jquery/gl-dependency-scanning-report.json and qa/expect/js-npm/minified-jquery/default/gl-sbom-npm-npm.cdx.json to qa/expect/js-npm/minified-jquery/default/.
• Adding a new expectation to qa/expect/js-npm/minified-jquery/with-excluded-paths/gl-dependency-scanning-report.json to check the scenario when DS_EXCLUDED_PATHS is set to JSONSelect.

See this discussion for more details.
