On Ubuntu 24.04 with Python 3.12 two regexes showed the warning about
invalid escape sequences:
```
aptly/publisher/__init__.py:179: SyntaxWarning: invalid escape sequence '\}'
nodes_raw = re.findall('[ \t]+"([^"]+)".*label="{(Repo|Snapshot|Published) ([^|]+)[^\}"]+}"', dot_data)
aptly/publisher/__init__.py:591: SyntaxWarning: invalid escape sequence '\ '
parsed = re.match('(.*)\ (.*)\ (.*)\ (.*)', ref)
```
Fix those regexes by removing the not needed escapes `\`.
- the `}` inside the `[]` grouping doesn't need to be escaped
- from: https://docs.python.org/3/howto/regex.html#matching-characters
- Metacharacters (except `\`) are not active inside classes.
For example, `[akm$]` will match any of the characters 'a', 'k', 'm', or '$';
'$' is usually a metacharacter, but inside a character class it’s stripped of its special nature.
- the space character ` ` doesn't need to be escaped
Tested on Ubuntu 18.04, 20.04, 22.04 and 24.04 with the `cleanup`
command (which uses the first regex) and the `dump` command
(which uses the second regex)
```sh
python3 -m aptly.publisher -v --url http://example.com/aptly cleanup
python3 -m aptly.publisher -v --url http://example.com/aptly dump --publish "all"
```
