Pull request overview

This PR reverts a previous build change that switched GitHub API authentication in build/lib/fetch.ts to use Bearer tokens, restoring the prior Basic-auth header construction.

Changes:

• Replaces Authorization: Bearer ${GITHUB_TOKEN} with a Basic header built from base64-encoding GITHUB_TOKEN.

Authorization is being set to Basic <base64(GITHUB_TOKEN)>, but GITHUB_TOKEN is a raw token (e.g. from gh auth token / Actions) and Basic auth requires a username:password credential string. This will produce an invalid Basic header and likely cause 401s for GitHub API/release asset requests. Use Authorization: Bearer ${process.env.GITHUB_TOKEN} (or token ${...}) instead of Basic/base64 here, consistent with other build scripts (e.g. build/azure-pipelines/common/checkDistroCommit.ts uses Bearer).

Suggested change

	ghApiHeaders.Authorization = 'Basic ' + Buffer.from(process.env.GITHUB_TOKEN).toString('base64');
	ghApiHeaders.Authorization = `Bearer ${process.env.GITHUB_TOKEN}`;
