Convince GitLab not to crop collapsed multiline strings (#3971)

Use of `- >` instead of `- |` workarounds GitLab quirk when it crops
collapsed multiline `script:` section commands in its CI job logs.
This PR also fixes `- |` based `script:` steps to behave properly after
`- >` conversion.

Resolves https://github.com/paritytech/ci_cd/issues/972.
