Bump golang.org/x/crypto and golang.org/x/oauth2

[cbandy]

Adds a script and uses it to bump some dependencies:

$ hack/go-get.sh -u golang.org/x/crypto golang.org/x/oauth2
go: golang.org/x/crypto@v0.35.0 requires go >= 1.23.0; switching to go1.23.6
go: golang.org/x/crypto@upgrade (v0.35.0) requires go@1.23.0, not go@go1.22.7 (1.22.7)
go: golang.org/x/oauth2@upgrade (v0.27.0) requires go@1.23.0, not go@go1.22.7 (1.22.7)

$ hack/go-get.sh -u golang.org/x/crypto golang.org/x/oauth2 go@go1.23.0
go: golang.org/x/crypto@v0.35.0 requires go >= 1.23.0; switching to go1.23.6
go: upgraded go 1.22.7 => 1.23.0
go: upgraded golang.org/x/crypto v0.31.0 => v0.35.0
go: upgraded golang.org/x/oauth2 v0.23.0 => v0.27.0
go: upgraded golang.org/x/sync v0.10.0 => v0.11.0
