releases/15.0R/relnotes: Use 13.0R formatting for "Sponsored by"

[olce]

Summary

We have been having some special formatting for "Sponsored by", which
for some reason has been abandoned since 14.0R.

Put it back, as it helps distinguish the content from the sponsoring.
It is also visually more pleasing (YMMV).

I am not sure but omitting the by as it implies that someone else sponsored "Netflix" or "The FreeBSD Foundation" or "Google" while it is the other way around. And I am still unsure about the difference between 13.0R and 14.0R as both shows the same "(Sponsored by ...)" just in italics in 13.0R.

In the source, yes, but the by appears in the generated HTML. Frankly, I do not know how that {{< ... >}} construct is substituted, so don't know if we could add by or not without changing anything else, or how to change how this markup is matched.

Would be better for the source to substitute {{< sponsored "..." >}} with {{< sponsor "..." >}}.

I'll have to look how to do that (and will be off the whole week-end). If someone knows, please share.

If it renders like https://www.freebsd.org/releases/13.0R/relnotes/ and not https://www.freebsd.org/releases/14.0R/relnotes/ looks good to me

Yes, it does.
