* Update docs/submodules/fuel from branch 'master'
  - Merge "[Horizon] Fix 'mcp' version check pattern"
  - [Horizon] Fix 'mcp' version check pattern

    Previous commit used a pattern that is too generic and always matches
    the substring 'mcp' vs the node hostname, not only pkg version.

    Fixes: 4658acf
