Description

reviving watch tower dappnode package?

cla workflow is bugged, see my comment below for workaround instructions

Changes

• bumped upstream version of watch-tower to latest
• some default linting
• bump cla workflow version, although bug that we are currently seeing in this pr might not be fixed. ref: [BUG] Error on first run: "Error: Could not retrieve repository contents. Status: 404" contributor-assistant/github-action#155

How to test

i was able to successfully run a dappnodesdk build, but dappnodesdk publish needs to happen from this repo's ci iiuc

Related Issues

fixes #1; however instead of bumping automatically it pins to latest version (for now)

cla workflow requires a branch cla-signatures with an empty signatures json. see workaround instructions here: cowprotocol/cla@7b90dc2
