Provide one common class for the current date range

[alanmels]

To highlight the date range containing the current date, I used the "starts-today" class shown on the html code below:

<td class="multi-day starts-today" colspan="2" rowspan="1" data-date="2023-09-03" >
  <div class="inner">
    <div class="item">
  <div class="view-item view-item-calendar ">
  <div class="calendar monthview">
        <div class="calendar-21-field_check_in-0.2 contents">
                      <div class="continuation">&laquo;</div>
                Logan [blurred]                      <a href="/reservation/4/hmsny3xb9p" class="active">HMSNY3XB9P</a>          </div>
        <div class="cutoff">&nbsp;</div>
      </div>
  </div>

and it works great when the current day is within the date range that is displayed in one row within the same <tr>, however when the date range is broken down into two parts then the styling also breaks like so:

The closest template I could use to get to rows (not fields) was the template_preprocess_calendar_month and the part that was not working for me where I injected a new class for styling purposes looks like this:

<td class="multi-day" colspan="2" rowspan="1" data-date="2023-09-01" >
  <div class="inner">
    <div class="item">
  <div class="view-item view-item-calendar ">
  <div class="calendar monthview">
        <div class="calendar-21-field_check_in-0.0 contents">
                      <div class="continuation">&laquo;</div>
                Logan [blurred]                       <a href="/reservation/4/hmsny3xb9p" class="active">HMSNY3XB9P</a>          </div>
        <div class="continues">&raquo;</div>
      </div>
  </div>
</div>
  </div>
</td>

but it was quite a "dirty" hack, so I thought to report this issue in hope that module maintainers could come up with better solution. Thanks for consideration!

Thanks @alanmels for reporting. I won't be able to spend much time on this, but if you've got chance to make a PR, I can test and review.

Well, I would definitely file a PR if I knew how to come up with more generic approach that would work for everybody else. In my use case, as I explained, I had to use "quite dirty" hack that won't work for other users.
