[Feature] Add support for disabling supports_block_receipts via environment variables

Description

Problem
Some blockchain nodes of specific chains return invalid data when calling the eth_getBlockReceipts method. This behavior can cause issues in the functionality of graph-node, particularly when the supports_block_receipts feature cannot be entirely disabled.

Currently, the environment variable GRAPH_ETHEREUM_BLOCK_RECEIPTS_CHECK_TIMEOUT allows configuring the timeout for block receipt checks. However, this is insufficient for completely disabling the functionality.

Proposed Solution
Introduce a new environment variable, such as GRAPH_SUPPORTS_BLOCK_RECEIPTS, to allow disabling the supports_block_receipts feature entirely by setting its value to false.

If the variable is not set, the current default behavior is preserved.
The variable would explicitly override the configuration to skip the supports_block_receipts checks.

Are you aware of any blockers that must be resolved before implementing this feature? If so, which? Link to any relevant GitHub issues.

Beginne damit, die Konfigurationsbehandlung für GRAPH_ETHEREUM_BLOCK_RECEIPTS_CHECK_TIMEOUT und die supports_block_receipts-Prüfungen zu finden; im Issue werden keine Dateien oder Tests genannt. Füge den vorgeschlagenen Override für die Umgebungsvariable hinzu und bewahre den bestehenden Standardwert, wenn sie nicht gesetzt ist; überprüfe anschließend, dass false die Prüfungen überspringt.
