### Bug description

The new version `3.349.3` of the AWS SDK for PHP used by Nextcloud 32 causes a regression bug in the case of multipart uploads in an S3-compliant storage backend. The AWS SDK for PHP `>=3.337.0` was released with changes to the S3 client that adopts new default integrity protections. Please refer to: https://github.com/aws/aws-sdk-php/discussions/3100

This change in the S3 client’s default settings causes a problem because multipart chunks are now being decorated with a checksum header that (some) S3-compliant storage backends reject as unexpected. I am not sure if other S3-compliant storage backends (MinIO, Garage Wasabi, …) behave in the same way, but uploads do no longer succeed with our Cloudian HyperStore.

I have made some modifications to the Nexcloud code in order to make the settings for the S3 client `request_checksum_calculation` and `response_checksum_validation` configurable when you encounter this issue. When you restore the previous default `"request_checksum_calculation": "when_required"` and `"response_checksum_validation": "when_required"` the issue is solved. I will provide a pull request as soon as possible.

### Steps to reproduce

1. Install Nextcloud 32 with an S3-compliant storage as primary backend
2. Upload a file >= 100 MB via WebUI


### Expected behavior

Uploading files with a size larger than the configured chunk size succeeds.

### Nextcloud Server version

32

### Operating system

Debian/Ubuntu

### PHP engine version

PHP 8.3

### Web server

Apache (supported)

### Database engine version

PostgreSQL

### Is this bug present after an update or on a fresh install?

Upgraded to a MAJOR version (ex. 31 to 32)

### Are you using the Nextcloud Server Encryption module?

None

### What user-backends are you using?

- [x] Default user-backend _(database)_
- [x] LDAP/ Active Directory
- [ ] SSO - SAML
- [ ] Other
