Cross account lakeformation tables in AWS

### Apache Iceberg version

0.11.1

### Please describe the bug 🐞

We have our datalake that is apache iceberg format that is governed by lakeformation (account A). We have various other AWS accounts that are trying to read in a lambda using pyiceberg.

All boto3 calls to fetch the data work correctly, to me verifying that the IAM permissions and Lake formation permissions are correct. Additionally boto3 athena calls are successful. However when pyiceberg, it fails with the following error:

`[ERROR] ForbiddenError: RESTError 403: Received unexpected JSON Payload:
{
"error": {
"code": 403,
"type": "AccessDeniedException"
}
}
, errors: Field required

File "/opt/python/lib/python3.13/site-packages/pyiceberg/catalog/rest/response.py", line 111, in _handle_non_200_response
raise exception(response) from exc`

here is the relevant piece of code:
` catalog = load_catalog(
"glue_rest",
**{
"type": "rest",
"uri": "https://glue.us-east-2.amazonaws.com/iceberg",
"warehouse": "account_A_account_number",
"rest.sigv4-enabled": "true",
"rest.signing-region": "us-east-2",
"rest.signing-name": "glue",
}
)

table = catalog.load_table("database1.table1")`

here is our settings:
AccountA:
- lakeformation describe on Database
- lakeformation describe, select on relevant tables
- have a proper data location access resource create in lakeformation granting the execution role the appropriate access

AccountB:
- lambda execution role has glue:* and lakeformation:GetDataAccess

Just to note, the catalog is created successfully and doesn't throw an error, but it does when we specifically on load_table()

I've tried troubleshooting by playing with the headers being sent and messing with the header value sig4-enabled. Nothing seems to work.

Does anyone have a working example and the configuration you are using? Is this support with the current version (we are on latest 0.11.1).

Any help would be appreciated. I can provide additional information if needed.
