apt : apt::source parameters do not match the naming convention in sources.list

the `apt::source` resource uses the following parameters to define a sources.list entry:

• location
• release
• repos

This naming convention is confusing:

1. a machine might run a given release, but can also have different suites configured. in this case using release is ambiguous and causes confusion such as https://github.com/puppetlabs/puppetlabs-apt/pull/905 - suite should be used here instead
2. a repo is normally what a sources.list entry points at, it's not /part/ of a repo - components is the proper wording here
3. location is okay, but is usually called uri in the apt documentation

The upstream documentation is here:

https://manpages.debian.org/buster/apt/sources.list.5.en.html

It specifically gives this example:

deb [ option1=value1 option2=value2 ] uri suite [component1] [component2] [...]

deb-src [ option1=value1 option2=value2 ] uri suite [component1] [component2] [...] 

I would propose that we switch from location, release, repos to:

• uri
• suite
• components

This would be an API-breaking changes, but could be introduced in a backwards compatible way, with deprecation warnings that would get dropped at a major release.

(I would also add an options hash to allow arbitrary options to be passed into the sources.list, but that's a different topic, which is covered by the discussion in https://tickets.puppetlabs.com/browse/MODULES-9695 )

Thanks!
