Pull request overview

Syncs eng/common pipeline templates with azure-sdk-tools (per azure-sdk-tools PR 14405), primarily to improve npm configuration/auth handling in common pipeline steps.

Changes:

• Add optional NpmConfigUserConfig pipeline parameter support and plumb it through as NPM_CONFIG_USERCONFIG in relevant steps.
• Extend create-authenticated-npmrc.yml with a SkipAuthentication parameter to optionally skip npmAuthenticate.
• Adjust npm publish job flow to create a .npmrc earlier (before branching on registry).

In npm-publish.yml the .npmrc is now created under $(ArtifactPath) for all registries, but the subsequent Verify tag after ESRP release step (npmjs.org branch) runs npm view ... without workingDirectory: $(ArtifactPath) (and without setting NPM_CONFIG_USERCONFIG). With the removal of the prior registry reset step, npm view may use the agent/global npm config instead of the intended registry, causing tag verification to query the wrong feed. Consider either setting workingDirectory: $(ArtifactPath) (or env: NPM_CONFIG_USERCONFIG=$(ArtifactPath)/.npmrc) on the verification step, or restoring an explicit registry override before running npm view.
