Deduplicate regex-automata #1175
Description
It looks like tracing-subscriber is pulling in an old version:
❯ cargo tree -p puffin -i regex-automata@0.1.10
regex-automata v0.1.10
└── matchers v0.1.0
└── tracing-subscriber v0.3.18
├── puffin v0.0.3 (/Users/crmarsh/workspace/guffin/crates/puffin)
└── tracing-tree v0.3.0
└── puffin v0.0.3 (/Users/crmarsh/workspace/guffin/crates/puffin)
Whereas elsewhere, we use regex-automata@0.4.4.
