minor updates to the 'From Source' page (#1222)

The part about "a wide array of architectures and operating systems"
predates the dependency on Envoy. Currently Pomerium is limited by the
OSes/architectures supported by Envoy, which I believe includes only
Linux and macOS, for amd64 and arm64. (According to an announcement at
https://groups.google.com/g/envoy-announce/c/2e-mSnit_BQ/m/VvweUrdaAAAJ
Windows is no longer supported after Envoy 1.27.)

As of pomerium/pomerium@faa2a86
golangci-lint is no longer required to be installed locally (it is
instead invoked via `go run`).

Finally, make sure "Pomerium" is capitalized consistently.

 # Building Pomerium From Source
 
-This document covers how to retrieve and build Pomerium from its source-code as well as how to run Pomerium using a minimal but complete configuration. One of the benefits of compiling from source is that Go supports building static binaries for a [wide array of architectures and operating systems](https://gist.github.com/asukakenji/f15ba7e588ac42795f421b48b8aede63).
