Rollup merge of #54989 - Munksgaard:fix-htmldocck-typos, r=tmandry

Fix spelling in the documentation to htmldocck.py

I was reading through htmldocck.py, and decided to attempt to clean it up a little bit. Let me know if you disagree with my edits.

 hyphens), and zero or more arguments separated by one or more whitespace

 There are a number of supported commands:
 
-* `@has PATH` checks for the existence of given file.
+* `@has PATH` checks for the existence of the given file.
 
   `PATH` is relative to the output directory. It can be given as `-`
   which repeats the most recently used `PATH`.
 
 * `@has PATH PATTERN` and `@matches PATH PATTERN` checks for
-  the occurrence of given `PATTERN` in the given file. Only one
-  occurrence of given pattern is enough.
+  the occurrence of the given pattern `PATTERN` in the specified file.
+  Only one occurrence of the pattern is enough.
 
   For `@has`, `PATTERN` is a whitespace-normalized (every consecutive
   whitespace being replaced by one single space character) string.
   The entire file is also whitespace-normalized including newlines.
 
   For `@matches`, `PATTERN` is a Python-supported regular expression.
-  The file remains intact but the regexp is matched with no `MULTILINE`
-  and `IGNORECASE` option. You can still use a prefix `(?m)` or `(?i)`

   the beginning and end of the file.
 
   (The same distinction goes to other variants of these commands.)

-  the presence of given `XPATH` in the given HTML file, and also
-  the occurrence of given `PATTERN` in the matching node or attribute.
