Upgrade the 'insta' dependency to version 1.37.0 to fix cargo audit warning

[jancionear]

Recently cargo audit started complaining that the yaml-rust dependency is unmaintained (#10876). yaml-rust is an indirect dependency that comes from the insta crate, so to fix the warning we must upgrade insta to a version that doesn't have this problem.
The insta crate just had a new release which fixes the problem detected by cargo audit (they pasted the whole yaml-rust crate into their tree x.x (mitsuhiko/insta#465)). We can upgrade to the latest version to get rid of the warning.

Upgrading to the latest version is relatively painless, I just had to replace assert_display_snapshot with assert_snapshot because assert_display_snapshot is now deprecated (see https://github.com/mitsuhiko/insta/blob/8379841b8fde1cbd2fee019a9207ebea3619658f/src/macros.rs#L372)

Fixes: #10876
