when committing to a token gated offer, check if the maxCommits condition has been reached

[levalleux-ludo]

At the moment, if the buyer owns the token(s) required by the token gating condition, the Commit button is enabled.
However, the condition also limits the number of commits that the buyer can perform. When this limit has been reached, the Commit button should be disabled
