Python 3.14

[Houbein]

Feature request to ask for Python 3.14 support.
The RC3 is out now, with no breaking changes expected between this and the final release next week.

Besides this request I want to bring attention to a legacy problem:
In this commit: 39bd3f6
Python version upper limit support was changed from major version to minor version, first released in library version 6.4.0
The result of this is that when I install robotframework-seleniumlibrary under Python 3.14 I do not get an error, I just get version 6.3.0, the last one before this stricter version lock.
I only noticed this by chance when I looked at a pip list today and thought "that version seems too old".
Now I get why you would want to be stricter with versions, but at the moment people are not being made aware of the version problem, they are just sleepwalking into using an old version.
All the more because our testset runs just fine with version 6.3.0 under Python 3.14 with no errors or warnings. Not that we have 100% keyword coverage.
My suggestion would be to either relax the Python version again, or backport warnings into older library versions so people are at least aware they are using an older version.

Fixed in #1950

Just made the v6.8.0 release which now allows for Python 3.14. This change removes the upper limit on the Python version so if one is starting to look at the next release, like 3.15, you should no longer be hampered in doing so.
