fix: benchmark references links

[antoineedy]

This small change makes benchmark reference links work as expected.

Here is a demo space of this PR: antoineedy/demo-mteb-leaderboard

The model links inside the tables have a strange behaviour as well; sometimes it opens a new tab, sometimes it shows a grey screen in the hugging face space.

In app.py (l.142), should I replace:

mteb/mteb/leaderboard/app.py

Line 140 in 6837be8

df["name"] = "[" + df["name"] + "](" + df["reference"] + ")"

by:
df["name"] = f'<a href="{df["reference"]}" target="_blank">{df["name"]}</a>'
to force a new tab to be created?

Yes, this is old bug and we can't figure out #2869. You can try to change it (probably without target)
