Change the package base name of the Go code, from
`git.blender.org/flamenco` to `projects.blender.org/studio/flamenco`.
The old location, `git.blender.org`, has no longer been use since the
[migration to Gitea][1]. The new package names now reflect the actual
location where Flamenco is hosted.

Avoid the word "error" in logging when Blender cannot be found. Typically
these are warnings, and having the word "error" there makes people think
otherwise.
For some reason, calling `AssocQueryStringW` on Windows Home returns error
code 122, "The data area passed to a system call is too small", even when
the data area is large enough. Furthermore, the API actually describes that
in such cases `S_FALSE` is supposed to be returned, with `*pcchOut` set to
the required size. Because of this apparent violation of the documentation,
and because it just works, Flamenco now ignores this particular error and
just returns the obtained string.
Blender Finder now understands that directory paths should be suffixed
with `blender` (Linux, macOS) or `blender.exe` (Windows).
Giving the Setup Assistant a path like `C:\Program files\Blender
Foundation\Blender 3.2` will now just work. This is considerably simpler
for many users, as copy-pasting a directory from a file explorer is
simpler than obtaining/typing the path to the executable.
When compiled without OpenColorIO, Blender will first complain "Color
management: Error could not find role data role." before showing the
actual version number. This is now handled by looking for a "Blender "
prefix instead of just returning the first line of output.
This has as a side-effect that when no such line can be found, we know
it's not Blender, and thus an error can be returned (instead of the
version of whatever binary was being run).
