Allow disabling the warning when dune detects a common typo

[kemsguy7]

This is a subtask for issue #11561 where users can make behaviour optional, defaulting to enabled

[gridbugs]

Fleshing out this description a little, this would be a follow-up to #11600. In the unlikely event that a user does intend to refer to the version number which is literally the string "version", they should be able to disable the warning that prints when common typos are found in dune-project. This could be implemented in the form of a new field in dune-workspace or dune-project or the user-wide dune-config file.
