fix hash computations (#111)

with Nushell 0.100.0, `to nuon` has changed and now quotes strings that
contain a `.`, thus breaking hash computations...

this PR does the following
1. formats the registry NUON file so that it's easier to read and
maintain
2. relax the "newline" test on registry files, not sure why we _want_ to
have newlines in registry files
3. fix the computation of the hash of pkg files by using `to nuon`
instead of `open --raw`
4. pin the Nushell version to 0.100.0 in the CI because having a moving
target in a CI is very hard to work with

> **Note**

> point 1, 2 and 3 are probably debatable and not mandatory for this PR
but it was by far the easiest to get this PR going 😋
