Release v0.200.0

[pietern]

Changes

This version marks the first version available as public preview.

The minor bump to 200 better disambiguates between Databricks CLI "v1" (the Python version)
and this version, Databricks CLI "v2". The minor version of 0.100 may look lower than 0.17
to some, whereas 200 does not. This bump has no other significance.

CLI:

• Add filer.Filer implementation backed by the Files API (#474).
• Add fs cp command (#463).
• Correctly set ExactArgs if generated command has positional arguments (#488).
• Do not use white color as string output (#489).
• Update README to reflect public preview status (#491).

Bundles:

• Fix force flag not working for bundle destroy (#434).
• Fix locker unlock for destroy (#492).
• Use better error assertions and clean up locker API (#490).

Dependencies:

• Bump golang.org/x/mod from 0.10.0 to 0.11.0 (#496).
• Bump golang.org/x/sync from 0.2.0 to 0.3.0 (#495).
