Twenty Seventeen: Calendar block header cells should be centered

[nkeller15]

The th elements in the Calendar block are not centered like the rest of the text in the Calendar which looks odd.

Added new code in the blocks.css file to fix this

[sabernhardt]

header cells are aligned left only when Calendar block is inside post content area

[sabernhardt]

the patch corrects the alignment on the front

[sabernhardt]

The Calendar block is not as likely to be used inside the post content area as within one of the widget areas in a "classic" theme such as Twenty Seventeen. The header cells already are centered where the block is expected.

That said, the patch works on the front end. If the styles are changed in blocks.css, then editor-blocks.css probably should have the same.

I would like to see this patch at least refreshed also to have it work for the editor before further consideration. I think there might be a case to add it if it doesn't break anything but benefits in the particular case, that said it needs to be both front and editor applied. Thank you everyone for your collaboration so far.
