Stop using 0pdd

[php-coder]

The rate of issues that I faced with pdd/0pdd is too high. Time to time, it tries to create a duplicate issues or close issues while the comments are still in place. Also the issues that have been reported don't have reaction from the maintainers for a long time.

Examples:

• https://github.com/yegor256/0pdd/issues/created_by/php-coder
• https://github.com/cqfn/pdd/issues/created_by/php-coder

Checklist:

• remove 0pdd bot from collaborators
• remove a webhook
• README.md: remove a badge
• remove .pdd and .0pdd.yml files
• add a record to decision log
• update changelog

Idea: a simple shell script build around git show | grep @todo and github cli tool can be used instead.

Here is how issues can be created/closed:

• https://cli.github.com/manual/gh_issue_create
• https://cli.github.com/manual/gh_issue_close

It seems 0pdd doesn't work anymore: it didn't create an issue for the commit bcb9402#diff-bc5be0d131b2f5510d9173cc14505d648eb85ce582a9dd78b6d460f4dc345d4cR2

GitHub Actions that can be helpfull:

• https://github.com/marketplace/actions/todo-to-issue
• https://github.com/marketplace/actions/track-todo-action
• https://github.com/marketplace/actions/todo-actions (inspired by 0pdd, but it isn't maintained; requires MongoDB for persistence)
• https://github.com/ribtoks/tdg-github-action

0pdd bot was removed from a list of collaborators. Also a webhook was removed as well.
