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.
