all: upgrade Unicode from 13.0.0 to 15.0.0

Update unicode/tables.go to reflect changes in the Unicode Standard up to Unicode 15.0.0, released 13 Sept 2022. In order to accommodate this update, strconv/isPrint has been updated to reflect changes in printable characters. Also changed is template/exec_test.go for both text and html packages- in the test "TestJSEscaping", rune U+FDFF was used as a placeholder for an unprintable character. This codepoint was assigned and made printable in Unicode 14.0.0, breaking this test. It has been replaced with the assigned and never-printable U+FFFE to fix the test and provide resiliency in the future. This upgrade bypasses Unicode 14.0.0, but is compatible. Updates golang#48621 Fixes golang#55079
