Update main description on landing page

[uekerman]

The old description was already a bit outdated missing volume coupling, multi-scale, ...
I tried to also remove aspects to not increase the overall length.

@uekerman Something that occasionally comes up during the workshop is the question of which units are used for time and data. It could be helpful to add the term unit-less in the intro to convey early that there is no limitation from preCICE.

Looks very good and very much needed, thanks! The "and ecosystem" addition in the description is also very-very much appreciated. 🙏

The drop of "fluid-structure interaction and conjugate heat transfer" is also very much due.

There are also a few more places to update this information. Non-exhaustive list:

• https://github.com/precice/.github/tree/main/profile/README.md
• Description of https://github.com/precice/precice
• A few places where preCICE is listed as a package

Suggested change

	preCICE is an <strong>open-source coupling library and ecosystem</strong> for general partitioned multi-physics and multi-scale simulations, including, surface coupling and volume coupling.
	preCICE is an <strong>open-source coupling library and ecosystem</strong> for general partitioned multi-physics and multi-scale simulations, including surface coupling and volume coupling.

I would even make it:

	preCICE is an <strong>open-source coupling library and ecosystem</strong> for general partitioned multi-physics and multi-scale simulations, including surface and volume coupling.

(to me, this reads more easily and compactly, even if more vaguely)

This is important, you are right. As it is a detail (the description does not imply dimensions anyway), should we maybe have a related "feature block" below?

See also an older related issue that was closed because it was rather impossible to address at scale: #31

Thinking about it a bit more, I think this is more suitable for the big picture page.

The features need some improvement marketing wise. But that is for another day.
