fix list formatting

[fdncred]

Types like floats weren't getting formatted properly in lists. It should've been respecting the float_precision: x in the config.nu file.

Example: broken

> seq 1.0 0.1 2.0 
╭────┬────────────────────╮
│  0 │ 1                  │
│  1 │ 1.1                │
│  2 │ 1.2                │
│  3 │ 1.3                │
│  4 │ 1.4                │
│  5 │ 1.5                │
│  6 │ 1.6                │
│  7 │ 1.7000000000000002 │
│  8 │ 1.8                │
│  9 │ 1.9                │
│ 10 │ 2                  │

Example: fixed, where float_precision: 2 is set in config.nu

> seq 1.0 0.1 2.0 
╭────┬──────╮
│  0 │ 1.00 │
│  1 │ 1.10 │
│  2 │ 1.20 │
│  3 │ 1.30 │
│  4 │ 1.40 │
│  5 │ 1.50 │
│  6 │ 1.60 │
│  7 │ 1.70 │
│  8 │ 1.80 │
│  9 │ 1.90 │
│ 10 │ 2.00 │
