symlink docs dirs for forc-mcp resources for publish CI (FuelLabs#7406)

## Description
This pull request adds a step to the CI workflow to link the `forc-mcp`
documentation into the Cargo target directory. This ensures that the
documentation is available in the correct location during the build
process.

Documentation integration:

* Added a CI job step in `.github/workflows/ci.yml` to create a symbolic
link for the `forc-mcp` documentation from
`docs/book/src/forc/plugins/forc_mcp/forc_call_tool` to
`target/docs/book/src/forc/plugins/forc_mcp/forc_call_tool`.
