Proposal: update location slack channels to have a common prefix for discoverability
Currently, it looks like we have the following location related channels:
- `#4corners`
- `#berlin`
- `#brazil`
- `#denver`
- `#dmv`
- `#france`
- `#holland`
- `#minnesota`
- `#nashville`
- `#netherlands`
- `#ny`
- `#philadelphia`
- `#poland`
- `#portugal`
- `#spain`
- `#sunshine_labbers`
- `#texas`
- `#uk`
- `#utah`
- `#valley`
For discoverability, I propose that we prepend these with `#loc_` similar to how we've grouped the `#lang_` and `#f_` channels.
