snapcraft.yaml: Update to "base: core20"

That is, switch to using Ubuntu 20.04 LTS as base,
leveraging new features in Snapcraft 4.x, etc.

It is far from complete, with npm temporarily disabled (hence no PostCSS)
and with Pandoc probably not working yet, but would hopefully get our
Hugo Snap build, which stopped working shortly after v0.80.0, working again.
