logger: unexpected error log when using TRACE level

[peczenyj]

when I am using the logger with TRACE mode to inspect what I am doing based on this documentation

that give the following options

Options: OFF , FATAL , ERROR , WARN , INFO , DEBUG , TRACE , ALL , NONE

if I set TRACE (instead DEBUG) I can see the following error log

time="2025-12-23T08:51:16Z" level=error msg="Log level 'TRACE' not recognized, using to default level INFO" @service=benthos

despite this message, the TRACE level works fine

I find the root cause: this line

BTW it is possible add support to TRACE levels using a dedicated code wrapper but it means changing all places where we create a new slog ( inside repo github.com/redpanda-data/benthos/v4 too )
