Remove whitespace character that was making example changesheet invalid

[eecavanna]

In this branch, I removed a whitespace character from the ID column of an example changesheet.

Details

The presence of that whitespace character made the changesheet invalid, from the perspective of the Runtime's changesheet validator.

Testing

• I tested these changes (explain below)
• I did not test these changes

I tested these changes by manually submitting the updated changesheet to https://api.microbiomedata.org/metadata/changesheets:validate and confirming that the Runtime considers the changesheet to be valid.

Documentation

• I have not checked for relevant documentation yet (e.g. in the docs directory)
• I have updated all relevant documentation so it will remain accurate
• Other (explain below)

Maintainability

• Every Python function I defined includes a docstring (test functions are exempt from this)
• Every Python function parameter I introduced includes a type hint (e.g. study_id: str)
• All "to do" or "fix me" Python comments I added begin with either # TODO or # FIXME
• I used black to format all the Python files I created/modified
• The PR title is in the imperative mood (e.g. "Do X") and not the declarative mood (e.g. "Does X" or "Did X")

Now that PR #845 has been merged in, the automated tests will run on this PR, since this PR includes changes to files in the paths (now) listed in the GHA workflow configuration file on the main branch.

With the changesheet having been updated as it has been in this PR, the automated tests now all pass. I will merge this in and shift my focus to the PRs that were opened earlier today (one of which introduces a pytest "skip" that would skip this then-failing test).
