Installing extras generates "filesize()" error messages

Bug report

Summary

Installing extras in a new 3.0.4 site generates the following type of error message :

[2023-12-14 15:20:26] (ERROR @ /www/core/src/Revolution/Transport/modTransportPackage.php : 433) PHP warning: filesize(): stat failed for https://modx.s3.amazonaws.com/extras/475/ultimateparent-2.0-pl.transport.zip?revolution_version=Revolution-3.0.4-pl
[2023-12-14 15:20:26] (ERROR @ /www/core/src/Revolution/Transport/modTransportPackage.php : 756) PHP warning: A non-numeric value encountered

amazonaws is the most frequent URL in these messages, but some extras generate errors with a different one, for example "modx-sentinel-prod.nyc3.digitaloceanspaces.com". The errors get logged after downloading an extra, prior to installing it.

Step to reproduce

Install an extra in 3.0.4, then check the error log
