Subject: [PATCH] tac: fix crash-loop by installing GNU sed for sed command
 compatibility

The TAC mainnet container was crash-looping with 'sed: unsupported command ^'
because busybox sed in Alpine does not support the GNU sed extensions used in
the cometbft-common.sh scripts (address ranges with ^ anchor and {} grouping).

Adding the 'sed' package installs GNU sed which supports these features.
