[BUG] deserialization error exposes sensitive values in the logs

[dracarys18]

Bug Description

When there's a deserialization error from external systems serde exposes even the sensitive values in the logs.

For example a deserialization error from card locker:-

Unable to parse router::core::payment_methods::transformers::GetCardResponse from bytes b\"{\\\"card\\\":{\\\"cardId\\\":\\\"08657065-fa64-abcd\\\",\\\"externalId\\\":\\\"abcdefghijkl\\\",\\\"merchantId\\\":\\\"merchant1\\\",\\\"cardNumber\\\":\\\"121312313131313131\\\",\\\"cardExpYear\\\":\\\"25\\\",\\\"cardExpMonth\\\":\\\"10\\\",\\\"nameOnCard\\\":\\\"name\\\",\\\"cardFingerprint\\\":\\\"2602abcbabcabcabc\\\",\\\"cardGlobalFingerprint\\\":\\\"fafafafafafaf\\\",\\\"nickname\\\":\\\"hyperswitch\\\",\\\"customerId\\\":\\\"Customer123\\\"}}\"\n│\n╰─▶ \u001b[1mnot a valid credit card number at line 1 column 157\u001b[22m\n

Expected Behavior

It should ideally mask the values in the logs like

Unable to parse router::core::payment_methods::transformers::GetCardResponse from bytes b\"{\\\"card\\\":{\\\"cardId\\\":\\\"08657065-fa64-abcd\\\",\\\"externalId\\\":\\\"abcdefghijkl\\\",\\\"merchantId\\\":\\\"merchant1\\\",\\\"cardNumber\\\":\\\"*****3131\\\",\\\"cardExpYear\\\":\\\"**\\\",\\\"cardExpMonth\\\":\\\"**\\\",\\\"nameOnCard\\\":\\\"***\\\",\\\"cardFingerprint\\\":\\\"2602abcbabcabcabc\\\",\\\"cardGlobalFingerprint\\\":\\\"fafafafafafaf\\\",\\\"nickname\\\":\\\"hyperswitch\\\",\\\"customerId\\\":\\\"****\\\"}}\"\n│\n╰─▶ \u001b[1mnot a valid credit card number at line 1 column 157\u001b[22m\n

Actual Behavior

Exposes even the sensitive values in the logs

Steps To Reproduce

Manually insert a wrong value into the database and try to fetch it with application. You will see a parsing error with the values exposed
