Bump go.mod version

[rabbitprincess]

The current go.mod version is 1.17, which is already 3 years old.
To support new dependencies such as pebbledb, it is good to update to Go 1.22+.

Makes sense. In the past we held off, as a big user of the packages also uses gopherjs for transpilation, which doesn't yet support any of the new generics features: #1986 (comment).

Based on this latest comment, it looks like they now support generics via an experimental build flag: gopherjs/gopherjs#1013 (comment). Given that, I think we should consider updating to Go 1.22, as we usually lag behind the latest by one release version.

@Roasbeef Can I submit a PR for this issue? Updating only go.mod without any dependency seems quite simple.
