OpenSSH announces DSA-removal timeline

For those of you still using DSA keys with SSH: the project has announced
its plans to remove support for that algorithm around the beginning of
2025.

The only remaining use of DSA at this point should be deeply legacy
devices. As such, we no longer consider the costs of maintaining
DSA in OpenSSH to be justified. Moreover, we hope that OpenSSH's
final removal of this insecure algorithm accelerates its
deprecation in other SSH implementations and allows maintainers of
cryptography libraries to remove it too.
