Poetry: Environment name regex pattern could be more precise

[karthiknadig]

Problem

The regex pattern used to identify Poetry environments by name is slightly permissive and could potentially match non-Poetry environments.

Current Code

// pet-poetry/src/lib.rs L32
static ref POETRY_ENV_NAME_PATTERN: Regex = Regex::new(r"^.+-[A-Za-z0-9_-]{8}-py.*$")

Issue

Poetry uses a specific naming convention: {name}-{8-char-hash}-py{major}.{minor}

The current pattern:

1. Uses py.*$ which would match py, pyxyz, py3, etc.
2. Should be more specific to match py{major}.{minor} format

Expected Pattern

Poetry's actual naming pattern creates names like:

• myproject-AbCdEf12-py3.10
• demo-project-XyZ78901-py3.11

A more precise pattern would be:

r"^.+-[A-Za-z0-9_-]{8}-py\d+\.\d+$"

Impact

Low - but could cause false positives in edge cases where a non-Poetry virtualenv happens to have a name matching the loose pattern.
