Thanks!

Some general stylistic comments:

1. You left some whitespace-only blank lines and spaces at the end of
   lines. Please, clean them up.
2. Please, use double space between sentences in the commit message and
   link to this thread. See
   https://orgmode.org/worg/org-contribute.html#commit-messages
3. I noticed some (let((...) forms. Please put spaces between sexps like
   (let ((...)
       ^ space here

> * lisp/org-element (org-element-timestamp-parser): Add :range-type property

Dot is missing at the end of the sentence here.

Here, you are manually constructing time part of the timestamp,
bypassing `org-time-stamp-format' and `org-timestamp-formats'. Please,
use `org-time-stamp-format' for times as well.
If necessary, feed free to extend `org-time-stamp-format' and the value
of `org-timestamp-formats' constant.

`string-replace' is fragile here. If we ever need to put "<" or ">"
inside timestamp, random breakages may happen. Please, rewrite.

Interpreting timestamps with :time-range nil and
:day-end/:year-end/:month-end non-nil as timerange is a breaking change.
Let's avoid it.

With the new version of the parser, the test example will never happen,
but the tested AST structure might happen in the wild - we do not want
to break anything when it is not necessary.
