Kate editor on Windows showing raku syntax highlighting issue

Syntax highlighting appears confused by the [word quote](https://docs.raku.org/language/quoting#index-entry-%3C_%3E_word_quote) construct `< >`.

The following example illustrates the issue:

~~~raku
# x, xx, o, X, Z are not used here as operators
# but are highlighted as such inside the word
# quote construct < >

my @array = [ 'x', 'xx', 'xxx', 'o', 'oo', 'X', 'Y', 'Z' ];
my @array = <  x    xx    xxx    o    oo    X    Y    Z  >;
~~~

This issue is observed on Windows with Kate 22.08.1 and on macOS via nix and pandoc.

$i < 1
$i + < 1
     ^ string delimiter
```

- fix some pattern in regex
- fix adverb argument
- ....
