Let's change the icon to our browser-group icon.
I'm not sure where else it's used (We talked about removing the option from the hamburger menu) but other occurences should be replaced too.

Pushed brave/brave-core#26925 but it seems current master doesn't have browser-group icon yet.
Maybe we need nala bump for this?

[aguscruiz]

Yeah, we need a bump, I just created that icon today 😬

It seems latest nala bump doesn't include this - brave/brave-core#26995

@simonhong we'll probably want this one uplifted into 1.74.x as it's a C132 regression. Only if it's a simple uplift though. Probably shouldn't be bumping/upgrading Nala at this point as we always run into UI regressions throughout the browser when that happens. Should do that earlier in the cycle when needed. If this requires a Nala upgrade, we should wait and let it ride the trains via 1.75.x. If we can get a simple fix as per https://github.com/brave/brave-core/pull/26925/files, we can get this uplifted into 1.74.x.

@kjozwiak This change depends on latest Nala bump.

[kjozwiak]

Gotcha, thanks @simonhong 👍 In that case, we can let this ride the trains. It's a really minor issue and uplifting nala introduces too much risk at this point re: fixing something minor as the above.

Tab groups icon on the bookmarks bar seem clipped. Visually the icon doesn't seem to match to Figma design as it has more rounded corners than the icon shown - Failed
