$stripteaser documentation incorrect

[GaryJ]

For the_content() and get_the_content() functions, the @param tag for $stripteaser is listed as a string, yet the default value is an integer, and the actual usage is as a boolean.

The deprecated the_content_rss() lists it as an int|bool.

* @param string $stripteaser Optional. Teaser content before the more text.

should be updated in both cases to something like:

* @param bool $stripteaser Optional. Strip teaser content before the more text. Default is false.

and set the default value from 0, to false, to make it clear that this is a boolean flag.

Within get_the_content() the line where $stripteaser is set to 1, should be changed to being set to true, just as the $hasTeaser boolean variable above it does. Clearer intention of a variable is worth a few extra bytes.

Show teaser content in ticket description should be Strip teaser content as per the attachment.

Correctly document $stripteaser as a boolean flag. Props GaryJ, fixes #18886.
