Add --seed flag to venv to allow seed package environments (#865)

Browse source 
## Summary

Installs the seed packages you get with `virtualenv`, but opt-in rather
than opt-out.

Closes https://github.com/astral-sh/puffin/issues/852.

## Test Plan

```
❯ ./scripts/benchmarks/venv.sh
+ hyperfine --runs 20 --warmup 3 --prepare 'rm -rf .venv' './target/release/puffin venv' --prepare 'rm -rf .venv' 'virtualenv --without-pip .venv' --prepare 'rm -rf .venv' 'python -m venv --without-pip .venv'
Benchmark 1: ./target/release/puffin venv
  Time (mean ± σ):       4.6 ms ±   0.2 ms    [User: 2.4 ms, System: 3.6 ms]
  Range (min … max):     4.3 ms …   4.9 ms    20 runs

  Warning: Command took less than 5 ms to complete. Note that the results might be inaccurate because hyperfine can not calibrate the shell startup time much more precise than this limit. You can try to use the `-N`/`--shell=none` option to disable the shell completely.

Benchmark 2: virtualenv --without-pip .venv
  Time (mean ± σ):      73.3 ms ±   0.3 ms    [User: 57.4 ms, System: 14.2 ms]
  Range (min … max):    72.8 ms …  74.0 ms    20 runs

Benchmark 3: python -m venv --without-pip .venv
  Time (mean ± σ):      22.5 ms ±   0.3 ms    [User: 17.0 ms, System: 4.9 ms]
  Range (min … max):    22.0 ms …  23.2 ms    20 runs

Summary
  './target/release/puffin venv' ran
    4.92 ± 0.20 times faster than 'python -m venv --without-pip .venv'
   16.00 ± 0.63 times faster than 'virtualenv --without-pip .venv'

Benchmark 1: ./target/release/puffin venv --seed
  Time (mean ± σ):      20.2 ms ±   0.4 ms    [User: 8.6 ms, System: 15.7 ms]
  Range (min … max):    19.7 ms …  21.2 ms    20 runs

Benchmark 2: virtualenv .venv
  Time (mean ± σ):     135.1 ms ±   2.4 ms    [User: 66.7 ms, System: 65.7 ms]
  Range (min … max):   133.2 ms … 142.8 ms    20 runs

Benchmark 3: python -m venv .venv
  Time (mean ± σ):      1.656 s ±  0.014 s    [User: 1.447 s, System: 0.186 s]
  Range (min … max):    1.641 s …  1.697 s    20 runs

Summary
  './target/release/puffin venv --seed' ran
    6.67 ± 0.17 times faster than 'virtualenv .venv'
   81.79 ± 1.70 times faster than 'python -m venv .venv'
