In PR #26786, the Go version for golangci-lint is bumped to 1.21. This
causes the following error:
```
models/migrations/v1_16/v210.go:132:23: SA1019: elliptic.Marshal has been deprecated since Go 1.21: for ECDH, use the crypto/ecdh package. This function returns an encoding equivalent to that of PublicKey.Bytes in crypto/ecdh. (staticcheck)
PublicKey: elliptic.Marshal(elliptic.P256(), parsed.PubKey.X, parsed.PubKey.Y),
```
The change now uses [func (*PublicKey)
ECDH](https://pkg.go.dev/crypto/ecdsa#PublicKey.ECDH), which is added in
Go 1.20.
