Scoped registries are duplicated

[AlexMeah]

Description:

When scope is specified and a matching scoped registry exists in .npmrc the registry entry is duplicated.

Action version:
3.4.1

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
Node 14
NPM 6

Repro steps:
Add an .npmrc with @scope:registry=https://example.com/ and an action with registry: https://example2.com and scope: scope.

Expected behavior:
The scoped registry should be overwritten by the action config.

Actual behavior:
The registry is duplicated and the first entry takes precedence.
