Support a single directory traversal in RelativeLinkFilter

Prior, if we were viewing a blob at
`https://example.com/namespace/project/blob/master/doc/some-file.md` and
it contained a relative link such as `[README](../README.md)`, the
resulting link when viewing the blob would be:
`https://example.com/namespace/project/blob/README.md` which omits the
`master` ref, resulting in a 404.

Fixes https://gitlab.com/gitlab-org/release-tools/issues/3

See merge request !2247

Help "SSH" fixes

A user was confused why ssh login did not work because he had used a nonstandard name during the key generation step. Maybe this will make it clearer.

See merge request !2296

Users must not change the default filename or they will have to create a
suitable .ssh/config which is out-of-scope here.

The keytype field is actually `ssh-dss` for DSA keys and they will not
be stored as `id_rsa.pub`.

Note that newer version of ssh actually also support
`ecdsa-sha2-nistp256` and others so it is also misleading to assume the
field always starts with `ssh-`.
