fix: remove hardcoded bearer

[marco-ippolito]

Followup of #1240

Description:
This change makes the mirror usable.
Right now Immagine we setup the value of mirror-token to foo.
In this line the value is used as

setup-node/src/distributions/base-distribution.ts

Line 106 in 2951748

headers['Authorization'] = `Bearer ${this.nodeInfo.mirrorToken}`;

Bearer foo but in other places such as:

setup-node/src/distributions/base-distribution.ts

Line 149 in 2951748

this.nodeInfo.mirrorToken

setup-node/src/distributions/base-distribution.ts

Line 210 in 2951748

this.nodeInfo.mirrorToken

its used as is.

But if we change the value to Bearer foo,

setup-node/src/distributions/base-distribution.ts

Line 106 in 2951748

headers['Authorization'] = `Bearer ${this.nodeInfo.mirrorToken}`;

here it becomes Bearer Bearer foo which is incorrect, but works everywhere else.

So this PR makes it that if its a Bearer, the user needs to be explicit.

Pull request overview

This PR fixes an inconsistency in how the mirror-token is used across the codebase. Previously, the token was hardcoded with a "Bearer" prefix in one location (getNodeJsVersions method) but used as-is in all other locations (downloadTool calls). This inconsistency made the mirror feature unusable because users had to choose between making one call work or the others. The fix removes the hardcoded "Bearer" prefix, requiring users to explicitly include the authentication scheme in their token if needed.

Changes:

• Removed hardcoded "Bearer" prefix from Authorization header in getNodeJsVersions method
• Updated compiled distribution file to reflect source changes
