Add custom datetime format through strftime strings (#9500)
- improves usability of datetime's in displayed text
-
# Description
Creates a config point for specifying long / short date time formats.
Defaults to humanized as we have today.
Provides for adding strftime formats into config.nu such as:
```nu
datetime_format: {
normal: "%Y-%m-%d %H:%M:%S"
table: "%Y-%m-%d"
}
```
Example:
```bash
> $env.config.datetime_format
┏━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ normal ┃ %a, %d %b %Y %H:%M:%S %z ┃
┃ table ┃ %m/%d/%y %I:%M:%S%p ┃
┗━━━━━━━━┻━━━━━━━━━━━━━━━━━━━━━━━━━━┛
> let a = (date now)
> echo $a
Thu, 22 Jun 2023 10:21:23 -0700
> echo [$a]
┏━━━┳━━━━━━━━━━━━━━━━━━━━━┓
┃ 0 ┃ 06/22/23 10:21:23AM ┃
┗━━━┻━━━━━━━━━━━━━━━━━━━━━┛
```
# User-Facing Changes
Any place converting a datetime to a user displayed value should be
impacted.
# Tests + Formatting
- `cargo fmt --all -- --check` Done
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` Done
- `cargo test --workspace` Done
- `cargo run -- crates/nu-std/tests/run.nu` Not done - doesn't seem to
work
```bash
> use toolkit.nu # or use an `env_change` hook to activate it automatically
> toolkit check pr
``` - Done
