Typo: tls.cert_file should be tls.crt_file in the Open Telemetry output docs

[LiamDavey]

tls.cert_file should be tls.crt_file in Open Telemetry output docs - https://docs.fluentbit.io/manual/data-pipeline/outputs/opentelemetry

When using version 4.1 of fluent-bit, using the tls.cert_file setting results in error during startup. tls.crt_file works as per the description.

The tls documentation here https://docs.fluentbit.io/manual/administration/transport-security says tls.crt_file too

Think its just a typo in the docs.

thanks for raising this @LiamDavey :) looks like the same typo affects a few other pages as well, so I'm glad you caught it!
