update HISTORY.rst

[Mikejmnez]

• OceanSpy version:
  0.35

Description

We need to update the history to describe the new changes implemented from version 0.34 to 0.35, with references to PRs with proper acknowledge to contributors. This is simply an update to the documentation. The way I do this is the following:

• Run oceanspy within Sciserver. make sure that the new oceanography image and the fresh conda install of oceanspy work properly.
• Run the tutorial notebooks within Sciserver. This ensures that there are no errors, deprecation warnings, and that overall the notebooks looks the way they should.
• Follow the steps here https://oceanspy.readthedocs.io/en/latest/contributing.html#contributing-to-the-documentation. You can get the history from GH releases, but I like to write a paragraph that summarizes it in simple text...

I have some time this week and can do this myself. But I though it would be nice to write how I update the documentation.
