[release / github action]: Update release action to output full versions list

[jd239]

Summary

At the moment, the release github action partially outputs all the package versions which are updated during the release process. This is not enough to be confident with the up and coming versions and checks need to be done locally.

💬 Description

The requirement is to output the full version updates outputted by the lerna command and add it to the release PR summary. e.g.

Changes:
 - @ukic/canary-docs: 2.0.0-canary.0 => 2.0.0-canary.1
 - @ukic/canary-react: 2.0.0-canary.11 => 2.0.0-canary.12
 - @ukic/canary-web-components: 2.0.0-canary.11 => 2.0.0-canary.12
 - @ukic/docs: 2.10.1 => 2.10.2
 - @ukic/nextjs: 0.2.3 => 0.2.4 (private)
 - @ukic/react: 2.17.0 => 2.18.0
 - @ukic/web-components: 2.17.0 => 2.18.0

💰 Use value

There may be an issue with formatting once the output from npm run release-check is placed in a variable. Ideally it would be good if the format can stay as bullet points when displayed as the PR summary.
