Format the value on the total followers card

[irfano]

Fixes #19893

This adds a feature to format the Total Followers card by

• using comma for values greater than 999,
• using suffixes ("M", "B" etc.) for values equal to or exceeding 1M.

The Total Followers card's behavior is now the same as other total cards.

To Test:

@guarani, I only request reviewing screenshots from you.

1. Select a site with more than 999 followers.
2. Navigate to My Site → Stats.
3. If the Total Followers card is not visible on the INSIGHTS tab, add it from the ⚙️ icon at the top right.
4. Verify the value on the Total Followers Card is shortened by using suffixes.
5. Select a site with more than 999999 followers.
6. Repeat 2-4.

It looks like this has already been reviewed and merged, but I gave it a quick test and it certainly looks fixed. Thanks Irfan!
