Deduplicate regex-automata

[charliermarsh]

It looks like tracing-subscriber is pulling in an old version:

❯ cargo tree -p puffin -i [email protected]
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 [email protected].
