Laravel Deprecated error(s) on fresh install w/ PHP 8.4

[danielfowler]

Bug description

I'm running PHP 8.4 w/ Laravel Herd on a Windows 11 PC. On one fresh/blank Statamic install and two other v5 sites I'm getting this Laravel error across the top of every page:

Deprecated: Return type of Carbon\Traits\Date::createFromTimestamp($timestamp, $tz = null) should either be compatible with DateTime::createFromTimestamp(int|float $timestamp): static, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in D:\Websites\cast98\vendor\nesbot\carbon\src\Carbon\Traits\Timestamp.php on line 29

If I switch to PHP 8.3, the error goes away. Before doing that, I did run composer update which didn't affect the error.

There's also a slew of PHP Deprecation errors/warnings in my CLI which also running PHP 8.4.2 but I think that's out of scope for you gents.

How to reproduce

1. Install PHP 8.4
2. Run statamic new
3. Open local site in browser

Unfortunatley, we can't upgrade to Carbon 3 without making breaking changes so that'll need to wait for Statamic 6. You can either downgrade to PHP 8.3 or hide any deprecation warnings.

There's some more context on the PHP 8.4 PR.
