Merged PR 840170: removed beta version tag and set as latest from release pipeline

Bug in NPM release pipeline:

ESRP task releases package as beta because of package.json config
set as latest tasks adds latest tag
we end up with released package having both beta and latest tages.
Resolution:

We don't need to release beta versions - this tag is used for "pre-release or experimental" versions - we don't release such.
ESRP task will set latest tag when publishing the package if nothing else is configured (documentation )
no need for set as latest release pipeline stage after the above
