Can't enable trace level on docker built 1.7.0 image

[g-giordano]

starting with env vars:

environment:
RUST_BACKTRACE: full
RUST_LOG: reth_optimism_flashblocks=trace,info

Would result in:

op_reth | warning: some trace filter directives would enable traces that are disabled statically
op_reth | | reth_optimism_flashblocks=trace would enable the TRACE level for the reth_optimism_flashblocks target
op_reth | = note: the static max level is debug
op_reth | = help: to enable TRACE logging, remove the max_level_debug feature from the tracing crate
