Changed

• Updated buildpack dependencies.

Depends on #176 landing first, then this needs to be regenerated.

Triggered release:

[edmorley]

The size of the compressed .cnb file increased by 30% between 2.0.0 and 2.0.1:
https://github.com/heroku/procfile-cnb/releases/tag/v2.0.0
https://github.com/heroku/procfile-cnb/releases/tag/v2.0.1

We've also seen size increases upstream in libcnb.rs too - so I had a quick look into this.

The only changes in the release were dependency changes:
v2.0.0...v2.0.1

Using cargo-bloat (and rustc 1.72.0-beta.10)...

It looks like the main increases are:

• toml-related: 169 KB -> 370 KB (xref Large increase in binary size after upgrading to v0.7.6 toml-rs/toml#580)
• regex-related: 447 KB -> 521 KB (xref Ironing out regex-lite rust-lang/regex#961 (comment))
