fix(dateFilter, input): fix Date parsing in IE/Edge when timezone off…

…set contains `:`

When `Date.parse`-ing a date string, IE and Edge don't recognize the timezone offset in the format
`+HH:mm` (but only without the `:`). According to [the spec][1], the timezone offset should
contain `:`. The [ISO 8601 Standard][2] allows both forms (with and without `:`).
Although the `Date` implementation in JavaScript does not 100% follow the ISO 8601 Standard (it's
just _based on it_), all other browsers seem to recognize both forms as well.

Fixes #13880

Closes #13887
