C++ navbar links - add support for hyperlinks in `tuple[1]` field

[parker-research]

The following example appears to be supported in the Python documentation generation, but not in the C++ generation (using conf.py-style).

Specifically, using a direct URL link in the second tuple field.

LINKS_NAVBAR2 = [
    ("GitHub", "https://github.com/MikePopoloski/slang", []),
]

Would be awesome if it was supported the same in both generators!

• Supported: https://mcss.mosra.cz/documentation/python/#navbar-links
• Not supported: https://mcss.mosra.cz/documentation/doxygen/#navbar-links

What you suggest makes sense, this difference is likely due to the config being originally done through the Doxyfile where the flexibility was severely limited, and when I was making the Python theme I had a clean slate and could do it better from the start. I'll try to find time to unify behavior in both.

Until then, you should be able to do this instead. (Yes, I know, it's strange, but you can put even images there this way.)

LINKS_NAVBAR2 = [
    ("<a href=\"https://github.com/MikePopoloski/slang\">GitHub</a>", []),
]

Thanks!
