* Remove www.bharatkalluri.in from EXAMPLES.md
The footer and source code at <https://www.bharatkalluri.in/> state that
the site was made with Hugo, so it should be deleted as an example of a
Gutenberg site.
I considered also removing the link to https://adrien.is/, since the
link appears to be dead. But I left it for now, since that could be a
temporary outage.
If you would like, I'd be happy to format EXAMPLES.md as a table, which
might help keep it looking clean as it gets more entries.
* Convert EXAMPLES.md to table
This is extremely minor, but the initial `netlify.toml` example confused
me a bit because I didn't realize that it was using a *netlify*
variable; I thought I needed to replace something with a variable from
my own configuration. I made a very minor edit to the docs to clarify.
* Add `index page` section to documentation
The current documentation does not describe how to create a index page.
I initially found this confusing, because I expected an index page to be
a **page** rather than a section. Thus, I tried to access the page
content with `{{ page.content }}` and was very frustrated when I could
not.
This addition clarifies that the index page is **always** a section,
even if it does not have any sub-pages. This should also help people
who intend to use Gutenberg to build stand-alone webpages, rather than
blogs.
Add details to the templates/RSS page to clarify that the `rss.xml`
page is only generated if the `generate_rss = true` variable is set
in the site's `config.toml` page. This information is already present
in other parts of the documentation, but is not present in the RSS page,
which could be confusing.
This allows the easy generation of snaps as requested in #227.
This commit does not add automatic generation and publication of snaps
to the Snap Store, but they can easily be generated for local/personal
use by
```
snapcraft
sudo snap install gutenberg_xxx.snap
```
Add directories with snapcraft artifacts to `.gitignore`.
