[BUG] <2022-04-11 Mon 17:1-19:10> is wrongly parsed as a valid timestamp [9.5.3 (release_9.5.3-461-ga3dac4 @ /home/yantar92/.emacs.d/straight/build/org/)]

Hi,

Consider the following timestamp with a typo in starting minute:

<2022-04-11 Mon 17:1-19:10>

Running org-element-context yields a timestamp object with unexpected
properties:
(timestamp
 (:type active :raw-value "<2022-04-11 Mon 17:1-19:10>"
 :year-start 2022 :month-start 4 :day-start 11
 :hour-start nil :minute-start nil
 :year-end 2022 :month-end 4 :day-end 11
 :hour-end nil :minute-end nil
 :begin 1916 :end 1943 :post-blank 0))

Note that hour/minute values are nil.

Expected: The example timestamp is not parsed as a valid timestamp, but
rather considered a paragraph.

Best,
Ihor

Upon further thinking, I do not think that the above should be parsed as
a paragraph. We are rather permissive about extra unrecognized text in
the timestamps - it is a feature.

I, however, added a low-trust linter that reports timestamps with
unexpected extra text.

Handled.
