fix: change 'day' to 'Tuesday' in optimizing docs

In dependabot optimizing docs (https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/optimizing-pr-creation-version-updates), there is an example, for which the dependabot should run each Tuesday. However, in the explaining text it says that it should run 'every day', which is not correct.
