chore: Update dev deps specifiers (#535)

- Switch from tilde version constraints to using only an upper major
version bound. Since the lockfile already pins exact versions, the tilde
constraint is unnecessary and causes frequent (and unnecessary) Renovate
PRs.
- Use major-only upper-bound version specifiers for most development
dependencies.
- Keep the tilde specifier for Ruff and Mypy, since even minor updates
can—and often do—break CI.
