Add .agents/skills skill storage paths in documentation

[lewislbr]

Why:

As stated in stated in https://agentskills.io/client-implementation/adding-skills-support#where-to-scan, the .agents/skills paths are a convention for cross-client skill sharing.

These paths are already supported by VSCode Chat: https://code.visualstudio.com/docs/copilot/customization/agent-skills#_create-a-skill, and there seems to be a bug in the Copilot CLI github/copilot-cli#2161 that makes them partially supported.

What's being changed (if available, include any code snippets, screenshots, or gifs):

Added the .agents/skills project and personal paths.
