is_day() needs an inline doc description

[webdevmattcrom]

The name of this function and the title in the inline docs does not adequately describe the purpose of this function. Additionally, adding a description is useful/beneficial for DevHub.

Suggested Description:
"A conditional check to test whether the page is a date-based archive page."

Patch for ticket #42784 -- adds inline description per suggestion.

[webdevmattcrom]

Apologies, ignore the patch above. The description should be:
"A conditional check to test whether the page is a date-based archive page for the current day."

New patch being uploaded soon.
