Upcoming Breaking Changes

--Xvalidators-builder-registration-default-gas-limit is removed in favour of --validators-builder-registration-default-gas-limit

With the upgrade of the Prometheus Java Metrics library, there are the following changes:

Gauge names are not allowed to end with total, therefore metrics as beacon_proposers_data_total and beacon_eth1_current_period_votes_total are dropping the _total suffix
The _created timestamps are not returned by default.

Some JVM metrics have changed name to adhere to the OTEL standard (see the table below), Teku Detailed Dashboard is updated to support both names

Old Name	New Name
jvm_memory_bytes_committed	jvm_memory_committed_bytes
jvm_memory_bytes_init	jvm_memory_init_bytes
jvm_memory_bytes_max	jvm_memory_max_bytes
jvm_memory_bytes_used	jvm_memory_used_bytes
jvm_memory_pool_bytes_committed	jvm_memory_pool_committed_bytes
jvm_memory_pool_bytes_init	jvm_memory_pool_init_bytes
jvm_memory_pool_bytes_max	jvm_memory_pool_max_bytes
jvm_memory_pool_bytes_used	jvm_memory_pool_used_bytes

Default the gas limit to 36 million for externally produced blocks
Optimized blobs validation pipeline
