Change strings referencing `lbry.tv` in favor of `odysee.com`

Is your feature request related to a problem? Please describe.

Many strings still make a reference to the "lbry.tv" website, which no longer exists. These strings should be changed to "Odysee.com" to avoid confusion.

We can inspect all strings in the source code with this

grep -iR lbry.tv *
grep -iR lbry.tv * | wc -l

There are around 90 lines that contain "lbry.tv", of which some of them are strings in the user interface, and others are part of the code and comments.

Additional context

A user requested this in Discord, as he noticed the following string in the wallet page.

'A backup of your wallet is synced with lbry.tv.'

lbry-desktop/ui/component/walletBalance/view.jsx

Line 144 in eb56f1b

{__('A backup of your wallet is synced with lbry.tv.')}

As long as Odysee works as the online backup option for the LBRY Desktop wallet, the "lbry.tv" strings should be changed to "Odysee.com".
