[files_versions] Fix sidebar version item style

[julien-nc]

Give the version label a min width so it does not get invisible when the author name is long.
Make sure the overflow ofboth version label and author name are ellispsised.

Why not give it enough space for « Current version » to be shown entirely?

[julien-nc]

@tcitworld No reason. Anyway many translations of this string are longer and will be cut.
I can make it larger indeed. Waiting for more opinions.

Code wise ok, I would indeed make the label flex-grow with a max-width :)

@nextcloud/designers can you give us your opinion?

[jancborchardt]

Looks very nice @julien-nc! :)

Why not give it enough space for « Current version » to be shown entirely?

Agree with @tcitworld’s point – since the 100px width is an arbitrary value anyway, it might as well be a little bit wider so that our default texts are shown fully, at least in English. :)

@jancborchardt Changed the min-width and updated the screenshot.
