Sync grains

[mk-mxp]

• Run bin/configlet sync -u -e grains --yes --docs --filepaths --metadata --tests include (updates the Markdown files and maybe tests.toml)
  • docs: instructions unsynced: grains
  • metadata: unsynced: grains
• Drop strict types comments from test file and example code (these are useless)
• Add and sync test meta data to tests (uuid / #TestDox in DocBlocks)
• Move the comment about floats to a new .docs\instructions.append.md and adjust it to meet the current instructions wording. Vim script has such a file as an example
• Raise the difficulty to "medium" (4 or 5, it is 3 at the moment which is "easy")
• Add exercise to bin/auto-sync.txt to keep it in sync (keep the file alphabetically sorted)
• Decide on adding / adjusting / ordering test cases to match current problem specs

Do not redesign the student's interface or add test cases that would invalidate existing community solutions. These are extra tasks, which should be discussed in advance.

Hi @mk-mxp I would like to be assigned to this one too if it's available, but based on my schedule I will be able to start working on this after two weeks, if that's alright please assign me to it

@A-O-Emmanuel I'm glad you want to work on it. There is no "Date to finish" for these tasks.
