Format argument of `lubridate::as_date` doesn't work with non-standard date string in Lubridate 1.9.0.

[colinbrust]

In Lubridate 1.9.0, supplying a custom format string to as_date raises an error if a character is not prefixed by a "%". In the reprex below, a standard YYYY-MM-DD date string works, but adding any additional characters to the string raises an error. The same date conversion works with base R's as.Date:

lubridate::as_date("test2022-01-01", format="test%Y-%m-%d")
#> Error in h(simpleError(msg, call)): error in evaluating the argument 'x' in selecting a method for function 'as_date': Unknown formats supplied: tet
lubridate::as_date("2022-01-01", format="%Y-%m-%d")
#> [1] "2022-01-01"
as.Date("test2022-01-01", format="test%Y-%m-%d")
#> [1] "2022-01-01"
