update github.com/pelletier/go-toml to 1.2.0

**What this PR does / why we need it**:

Rationale: github.com/pelletier/go-toml is the only package that currently
prevents the future vendoring of github.com/golang/dep as it depends on
functions introduced in 1.1.0.

The only consumers of this package are github.com/spf13/viper (used to run e2e
tests) and github.com/bazelbuild/bazel-gazelle (bazel helper), so that's a
pretty low-risk change.

**Special notes for your reviewer**:

This should help reducing the noise when #64731 lands
