Before executing `buildah unshare` for mounting a container from scratch
as a non-root user, we need to export the variable `newcontainer` so
that it is known inside the modified user namespace.

Update tutorials to not expect `buildah run` to do anything if it isn't
given a command to run. In some cases (including when we need to listen
for incoming connections when we might well not be root) this means we
use `podman run` instead.
Try to avoid using the terms container and image as though they're
interchangeable, which just creates confusion.

Users have gotten confused when attempting the introduction turturial in
rootless mode. Explain that they have to `buildah unshare` before
mounting the image.

A bugzilla was created due to a misunderstaning gleened from the
Buildah tutorial. The person runing the tutorial followed it exactly,
but the example blew up on RHEL for them. The reason being is the
`--releasever` option has to use a valid version for the host's OS
when it's working on a scratch container or dnf will fail.
This adds clarifiction to the document to make that clear.

This is a partial fix for #1895. This focuses on (hopefully) helping a
user get into Buildah faster when they first hit the buildah.io site and
click down through the tutorials button. It also clarifies what's currently
out of scope for Buildah, adds some titles to make links easier and a bit more.
I expect I'll either be adding to this or creating a follow on PR to address more
of the notes in #1895.

Some operating systems don’t have `bash` in `/bin`, so we should take the
`$PATH` into consideration for searching it.

Before, there is no $newcontainer image committed thus
`podman run $newcontainer` attempts to pull $newcontainer from the various
container registries.

Get rid of dangling whitespace in markdown files, and add a quick

Adding command to explicitly become root user. I was trying to run commands with "sudo" in front and thus had issues following guide (new user) and this would have helped! Thanks!
