ecs-winston-format 1.5.0 is pulled in even though caret range set

builds of proof, principal, connection manager fail because package.json

"@elastic/ecs-winston-format": "^1.3.1",

caret range does not seem to have an effect strangely:

#13 13.24 dependencies:
#13 13.24 + @elastic/ecs-winston-format 1.5.0

3.927 src/utils/logger.ts:24:11 - error TS2349: This expression is not callable.

as a workaround, fix version. maybe commit a lockfile for ci builds?
