* Upgrade gqlgen to v0.17.2 This enables builds on Go 1.18. github.com/vektah/gqlparser is upgraded to the newest version too. Getting this to work is a bit of a hazzle. I had to first remove vendoring from the repository, perform the upgrade and then re-introduce the vendor directory. I think gqlgens analysis went wrong for some reason on the upgrade. It would seem a clean-room installation fixed it. * Bump project to 1.18 * Update all packages, address gqlgenc breaking changes * Let `go mod tidy` handle the go.mod file * Upgrade linter to 1.45.2 * Introduce v1.45.2 of the linter The linter now correctly warns on `strings.Title` because it isn't unicode-aware. Fix this by using the suggested fix from x/text/cases to produce unicode-aware strings. The mapping isn't entirely 1-1 as this new approach has a larger iface: it spans all of unicode rather than just ASCII. It coincides for ASCII however, so things should be largely the same. * Ready ourselves for errchkjson and contextcheck. * Revert dockerfile golang version changes for now Co-authored-by: Kermie <kermie@isinthe.house> Co-authored-by: WithoutPants <53250216+WithoutPants@users.noreply.github.com>
