website: Modernize and simplify language logic

[ziaee]

Summary

The website has really complex deprecated hugo logic for localization.
To simplify this and eliminate linter warnings, we first need a modern
hugo language key. Build that in hugo.toml, and remove all the extra
files related to the old way of doing this. This removes several INFO
messages about deprecated syntax during the build, increases clarity
of the build system, and allows us to begin transitioning off the
remaining deprecated elements.

removing the $ allows this line to be overridden. The hugo.toml already specifies the default, so no need to do so twice.

im almost sure we dont need this file at all, modern hugo does this for us, but i dont know enough yet to fix the logic that has to change if we remove this.

Note, this drops support for building the website with armv7. however, i would be astonished if anyone was doing that.

This is a much better approach

@ziaee I know this has dropped OK, but just wanted to say, don't get rid of baseof.html! I'm fairly sure it is the root of the whole template for Hugo. https://gohugo.io/templates/new-templatesystem-overview/#example-folder-structure

thanks for the doc! im interested in doing mechanical cleanup that produces no rendering change to unblock further development. im definitely not going to get rid of anything we need, and also going to wait on review from stakeholder teams, like this review will wait from translators.
