fix(scancode): No ScanCode license texts in disclosure document

If ORT is executed within a Docker container, the report generator for the
OSS disclosure document may not be able to look up the license texts
collected by ScanCode, leading to empty sections in the disclosure document.

In environments where Python version management tools like Pyenv are used,
directory structures differ, leading to different paths for data directories,
causing the reporter to fail looking up the ScanCode license texts.

Update the heuristic algorithm to locate the ScanCode license texts directory
based on the path of the ScanCode binary: Ensure compatibility with directory
layouts managed by Python version management tools.

Fixes #8147.
