Similar dependency broke our CI

Description

See https://github.com/gfx-rs/naga/pull/472/checks?check_run_id=1904641293#step:4:93

When testing on Rust-1.43.0, similar fails to build:

error[E0034]: multiple applicable items in scope
Error:   --> /home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/similar-1.2.0/src/algorithms/lcs.rs:25:18

Reproduction steps

1. Build 1.5.3 and up on Rust-1.43.0

Additional helpful information:

• Version of insta: 1.6.0
• Version of rustc: 1.43.0
• Operating system and version:

What did you expect

Not breakage

Notes

Of course we can work around this by either fixing the insta version to 1.5.2, or not building it on our MSRV. Just thought I'd fire up this bug to see your thoughts on it.

@kvark I'm sorry for that. I lowered the minimum requirements to 1.41.0 now which I think should be a good base for both similar and insta. Upgrading to 1.6.2 should fix it for you.

CI also now checks against 1.41.0 so this should not regress again.
