Update dependencies to support latest spdx-tools version

[persi0815]

Is your feature request related to a problem? Please describe.
Currently, the spdx-tools dependency is fixed at version 0.7.0rc0, which restricts compatibility with newer versions of scancode-toolkit and other related packages. This can lead to potential conflicts and limit the ability to benefit from updates and fixes available in later versions of spdx-tools.

Describe the solution you'd like
The desired solution is to adjust the dependency to allow for greater flexibility by setting it to spdx-tools>=0.7.0rc0. This change would enable the project to utilize any compatible version of spdx-tools from 0.7.0rc0 onwards, thereby improving compatibility and future-proofing the project against potential issues with newer versions of dependencies.
