$env.config now always holds a record with only valid values (#7309)
# Description
Closes #7059. Rather than generate a new Record each time $env.config is
accessed (as described in that issue), instead `$env.config = ` now A)
parses the input record, then B) un-parses it into a clean Record with
only the valid values, and stores that as an env-var. The reasoning for
this is that I believe `config_to_nu_record()` (the method that performs
step B) will be useful in later PRs. (See below)

As a result, this also "fixes" the following "bug":
```
〉$env.config = 'butts'
$env.config is not a record
〉$env.config
butts
```
~~Instead, `$env.config = 'butts'` now turns `$env.config` into the
default (not the default config.nu, but `Config::default()`, which
notably has empty keybindings, color_config, menus and hooks vecs).~~

This doesn't attempt to fix #7110. cc @Kangaxx-0

# User-Facing Changes

See above.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# After Submitting

If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
