Douglas 040a4eeaab Ability to specify a table name for kv commands (#16450)
Closes #15786 

## Release notes summary - What our users need to know

`std-rfc/kv` commands now take an optional `--table (-t)` argument which
allows a custom table name to be used. If not specified, the current
`std-kv-store` table will be used.

## Tasks after submitting

- [x] Added in-help example to `kv set`. Did not add examples to the
other `kv` commands since they should be obvious based on the initial
`kv set`.

## Additional details

Example:

```nushell
use std-rfc/kv *
kv set -t foo bar 5
kv list
# Empty list, since the value was placed in a custom table
# => ╭────────────╮
# => │ empty list │
# => ╰────────────╯
kv list -t foo
# => ╭───┬─────┬───────╮
# => │ # │ key │ value │
# => ├───┼─────┼───────┤
# => │ 0 │ bar │     5 │
# => ╰───┴─────┴───────╯
```

To protect against injection attacks, table names can only include
alphanumeric characters with `_` and `-`.

Welcome to the standard library of `nushell`!

The standard library is a pure-nushell collection of custom commands which provide interactive utilities and building blocks for users writing casual scripts or complex applications.

To see what's here:

> use std
> scope commands | select name description | where name =~ "std "
#┬───────────name────────────┬───────────────────description───────────────────
0│std assert                 │Universal assert command
1│std assert equal           │Assert $left == $right
2│std assert error           │Assert that executing the code generates an error
3│std assert greater         │Assert $left > $right
4│std assert greater or equal│Assert $left >= $right
             ...                                     ...
─┴───────────────────────────┴─────────────────────────────────────────────────

🧰 Using the standard library in the REPL or in scripts

All commands in the standard library must be "imported" into the running environment (the interactive read-execute-print-loop (REPL) or a .nu script) using the use command.

You can choose to import the whole module, but then must refer to individual commands with a std prefix, e.g:

use std

std log debug "Running now"
std assert (1 == 2)

Or you can enumerate the specific commands you want to import and invoke them without the std prefix.

use std ["log debug" assert]

log debug "Running again"
assert (2 == 1)

This is probably the form of import you'll want to add to your env.nu for interactive use.
