Fixing one of my frequent typos

[michaelhofrichter]

In this PR, I have:

• [X] Added tests for any new features or bug fixes (if relevant)
• [X] Added my changes to the CHANGELOG.md at the top, under the "Unreleased" section
• [X] Ensured issues that this PR closes will be automatically closed

Reason for this PR

Docassemble's Continue button has a capital C. When I write the tests, I consistently write it out to match that format. This clones the I tap to continue step so that it works with lower or upper case.

It also appears that my markdown linter is a little aggressive in reformatting the Changelog.

Links to any solved or related issues

None.

Any manual testing I have done to ensure my PR is working

None (sorry). One of the tests in Reports.feature is updated to use a capital I tap to Continue so if that still passes, all should be ok.

This is a great improvement and something that totally hadn't occurred to us! Thanks for this PR! If it's ok, I might tweak the implementation of the new step to avoid the duplicate code.
