Update Paket to v7.2.1

[Numpsy]

Paket updated with dotnet tool update paket.

Reasoning:

The 5.252.0 version it currently uses doesn't understand .NET 6, so it needs to be updated to a newer version.
As the new version still works with .NET 5, it could be updated as a stand alone step to reduce the number of changes needed later.

Hello Richard, thanks for your PR!

Does this fix anything in particular? Or, if not, does it pave the way for further fixes?

It was initially because I'd tried to update some deps like the compiler service to see what would happen with the build and got some warnings like

which I thought might be related to Paket not understanding those versions (they went away after the update in anycase, but my knowldge of Paket is rather small so maybe theres some other issue).

More generally though, the build is done with .NET 5 and I suppose it could do with updating to something more supported, for which updated tools should help

Actually on a related note - the global.json refers to version 5.0.202 of the SDK and I don't have that available on this system - I have to add a

"rollForward": "latestMinor"

to build it, so maybe that's something to look at as well

Ah yeah, I would merge a PR that updates to .NET6 given that v6 is LTS.

Yeah let's propose this in a different PR.

I'd enquired about the status of FSAutoComplete / Ionide integration in ionide/FsAutoComplete#942 and there are comments about it being broken due to the compiler libraries being out of step, so I thought i'd try to see how much difference there actually is (it doesn't build with the latest FCS, as seems to be expected)
