docs(migrations): simplify Azure storage wording

Remove the repeated use of 'storage' from Azure Blob Storage account references across migration guidance.

Changes:
- content/migrations/using-github-enterprise-importer/migrate-from-gitlab/configure-storage.md
  - Simplify the Azure Blob Storage account heading.
  - Normalize the file's missing end-of-file newline.

- content/migrations/using-github-enterprise-importer/migrating-between-github-products/migrating-repositories-from-github-enterprise-server-to-github-enterprise-cloud.md
  - Simplify the Azure Blob Storage account heading.

- content/migrations/using-github-enterprise-importer/migrating-from-bitbucket-server-to-github-enterprise-cloud/migrating-repositories-from-bitbucket-server-to-github-enterprise-cloud.md
  - Simplify the Azure Blob Storage account heading.

- data/reusables/enterprise-migration-tool/blob-storage-management-console.md
  - Simplify the shared Azure Blob Storage account reference.

Validation:
