Update template to work with CLI v0.210.1

[pietern]

• Fix the issue where starting v0.210.0 the permissions block is a valid top-level field in the bundle configuration. This template uses the same field as an anchor with a schema incompatible with the bundle configuration schema. This mismatch means none of the bundle commands work with this template starting with v0.210.1. To fix this, I renamed the field with the anchor block to common_permissions.
• Pin the Databricks CLI to a fixed version such that once automation is set up, it will continue to work.

Note: the whitespace changes are courtesy of VS Code settings:

  "files.insertFinalNewline": true,
  "files.trimFinalNewlines": true,
  "files.trimTrailingWhitespace": true,
