README: Why users cannot create issues directly

[nikitabobko]

Unfortunately, AeroSpace project doesn't accept bug reports and feature requests from everyone.

The submitted Issues are often either obvious duplicates, environmental problems, or configuration errors by the users themselves. For a hobby project, I don't have enough time and energy to process every such submitted Issue.

As an alternative, you can start a Discussion on GitHub discussions forum https://github.com/nikitabobko/AeroSpace/discussions. Any Discussion which clearly identifies a problem and can be confirmed or reproduced will be converted to an Issue by maintainers.

Thank you for your understanding.
