SourceRoot not Considered as Absolute Path

Describe the bug

Here is a small sample repo.

We try to use the sourceRoot to add the sources in a remote location so that we do not need to ship them. However, the mapping:

{"version":3,"file":"string.js","sourceRoot":"http:/raw.githubusercontent.com/SAP/cloud-sdk-js/main/packages/util/src/","sources":["string.ts"],"names":[],"mappings":";......"}

leads to an error because the CWD is added in front of the source route.

To Reproduce

• Checkout repo.
• Run install
• Execute debug-test.mjs via launch.json
• Step into method -> see the Error

Could not load source '/Users/XXX/source-map-test/node_modules/@sap-cloud-sdk/util/dist/http:/raw.githubusercontent.com/SAP/cloud-sdk-js/main/packages/util/src/string.ts': Unable to retrieve source content.
