No longer autoload deprecated-dirs (#14242)
# Description

Follow-up to #13842. In that commit, using one of the `dirs`/`shells`
aliases would notify the user that it would no longer be autoloaded in
future releases. This is the removal stage.

Side-benefit: Additional 1ms+ load time improvement

# User-Facing Changes

Breaking-change - `dirs` aliases are no longer autoloaded.

Users can either choose to continue using the aliases by adding the
following to the startup:

```nu
use std/dirs shells-aliases *
```

Alternatively, users can use the `dirs` subcommands (rather than the
aliases) with:

```nu
use std/dirs
```

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.
