chore: move docs

[AlexanderLanin]

This pull request introduces a new structure for component documentation and improves the way documentation bundles are built and organized. The most important changes include the addition of new docs_bundle build targets for the KVS and JSON components, a new centralized component documentation index, and updates to documentation references and paths to match the new organization.

Documentation build and structure improvements:

• Added docs_bundle build targets for KVS (kvs_docs) and JSON (json_docs) components in score/BUILD, specifying their source directories and code targets for more modular documentation builds.
• Updated the main BUILD file to include these new documentation bundles in the docs rule, mounting them at components/kvs and components/json respectively.

Documentation organization and navigation:

• Added a new docs/components/index.rst file serving as a central index for component documentation, including a needtable overview of all "score" documents.
• Updated docs/index.rst to reference the new component documentation index and adjusted paths for module/feature documentation to reflect the new directory structure. [1] [2]
• Updated internal references and paths in component documentation files (e.g., score/kvs/docs/index.rst and score/json/docs/index.rst) to match the new organization, removing redundant or outdated toctree entries. [1] [2]

These changes make the documentation more modular, easier to navigate, and better organized for both maintainers and users.
