php8: fixed a bug with # comments (#22)
Example from issue:
```php
<?php
#
# Comment
#

$a = 100;
```

The problem with the example from the issue is that `#` is immediately followed by a line break.
And since the rule in the lexer for such comments was changed, this case was handled incorrectly.

```
(('#' ^'[') | '//') any_line* when is_not_comment_end => {
   lex.ungetStr("?>")
   lex.addFreeFloatingToken(tkn, token.T_COMMENT, lex.ts, lex.te)
};
```

This rule has one problem, it checks two characters at once, first for the match `#`, and 
then for the mismatch `[`, which leads to the fact that in the case of an empty comment, the first 
matcher will capture `#`, and the second line break (`\n`), which will lead to the fact that `any_line` 
matcher will not work and will not increase the line number.

The next rule added is specifically for this case.

```
'#' newline when is_not_comment_end => {
    lex.ungetStr("?>")
    lex.addFreeFloatingToken(tkn, token.T_COMMENT, lex.ts, lex.te)
};
```
