fix(inputs.snmp_trap): Enable SHA ciphers

[JuhaKS]

Summary

SHA224, SHA256, SHA384 and SHA512 ciphers had been commented out when SNMPv3 support was implemented because they were not at that time yet sufficiently supported by gosnmp. Gosnmp has advanced and the ciphers are now fully working, so they can be added to the list of valid options for the snmp_trap plugin

Thanks!

Updated sample.conf and ran make docs to update the README.md to match

I verified the PR using our SNMP4J-based traffic generator to send events through Telegraf and verified the content of the events using Wireshark, output from Telegraf contained the original data unchanged. I manually tested the following combinations with AES256: SHA224, SHA256, SHA384 and SHA512. The code already had unit tests to cover the SHA ciphers so I just needed to take them into use
