add a button to copy image to clipboard

[RoyiAvital]

When using Plotly in Jupyter (Either with Python or Julia) I appreciate the interactivity of Plotly.
It is a great experience compared to Matplotlib.

Yet I miss the ability to copy the image into clipboard in a click.
I'd like to have a button, just like the Download PNG button which instead of downloading the file will copy the bitmap into the clipboard.

It seems users are looking for such feature, though for now they try creating a bypass:

• Allow plotly.py to define custom modebar buttons. #6060.
• customize modebar  plotly.py#2114.

I found that R users are also interested in this feature: https://stackoverflow.com/questions/72323149.

Any chance to have this feature added built in?

Good idea, I could even see this becoming a default addition to the modebar.

We have a lot of work in our queue already so would probably take us a while to get to this, but we'd gladly review a PR, should be a relatively straightforward addition.

I think browser compatibility around the clipboard API has only recently improved. I suspect that's the main reason this hasn't been implemented before. Here's an example showing how to do it for anyone who's interested in making a contribution.

ntegrated the latest changes from the remote master branch into the local repository.
Manually resolved merge conflicts in the following files:

.github/ISSUE_TEMPLATE.md

.gitignore

CONTRIBUTING.md

README.md

During the merge, preserved and integrated the local implementation of a custom modebar button example within the CustomBundle build, ensuring compatibility with the current Plotly.js codebase.
Also synced documentation and configuration files with upstream while maintaining local customizations.
