Adjust titles in polar projections overview

[michaelgrund]

Description of proposed changes

Adjust title for each plot so that the formatting looks like the string given to the projection parameter (double quotations are shown in the plot titles instead of single ones).

New:

Reminders

• Run make format and make check to make sure the code follows the style guide.
• Add tests for new features or tests that would have caught the bug that you're fixing.
• Add new public functions/methods/classes to doc/api/index.rst.
• Write detailed docstrings for all functions/methods.
• If wrapping a new module, open a 'Wrap new GMT module' issue and submit reasonably-sized PRs.
• If adding new functionality, add an example to docstrings or tutorials.
• Use underscores (not hyphens) in names of Python files and directories.

Slash Commands

You can write slash commands (/command) in the first line of a comment to perform
specific operations. Supported slash command is:

• /format: automatically format and lint the code

Looks good.

Hmm. I am a bit debating on what is more important, (i) using consistently double quotation marks for string arguments or (ii) making the title consistent with the argument. Currently, I am a bit more on the side of (i). A way to use both times double quotation marks is to add a leading \ for the inner double quotation marks. But maybe this makes things only more complicated.

Suggested change

	frame=["xa45f", '+gbisque+tprojection="P5c" @^ region=[0, 360, 0, 1]'],
	frame=["xa45f", "+gbisque+tprojection=\"P5c\" @^ region=[0, 360, 0, 1]"],

Backslashes make the codes more difficult to read and should be avoided.

Personally, I'm OK with displaying either single or double quotes in the plot title. Currently, single quotes are displayed like ’, rather than '. See #3476 for the reason and #3105 for the fix.

That's the reason why I wanted to change it. The single quotes are looking like accute accents right now and that's something that seems to be weird for users when they see it in plots. And yes, backslashes make the code more difficult and confusing.

Then it means we can close the PR without merging if #3105 is approved.

I would still go with using double quotations here since the titles directly reference the projection parameter in the code. Using single quotations for a string in such cases is fine in my opinion. But I'm also fine if all others what to keep it as is.

[seisman]

I'm inclined to keep it as is.

[yvonnefroehlich]

Would also prefer to keep it as is, as I prefer to have (if possible) double quotation marks for the string inputs.

I'm closing the PR.
