Add an 'update' entity to report new versions of the Frigate backend

[NickM-27]

Implements #235

Based off of WLED implementation as that is one of the few available for reference. Pre-requisite frigate PR is blakeblackshear/frigate#3038

@NickM-27 I'll leave this alone until the build passes -- just use the 'Request review' whenever you're ready.

Haha yeah it'll be a WIP, I may have some questions once I get further, but need to wait until the frigate PR is finalized since I've had some comments.

According to the update entity docs it can support showing the changelog, but it would need to pull it down separately and also has a max length 255 characters which is much shorter than frigate full releases typically are, so probably best to leave that out.

@dermotduffy It seems to be complaining that it can't find the update entity, I figured that the tests would automatically use the latest HA version?

Edit: I updated the reqs to require the newest HA

[NickM-27]

@dermotduffy I may need some help with these tests, not sure what changed in HA that makes media_source miss so many

[NickM-27]

@dermotduffy any thoughts on this? not sure if these tests are broken or if there is full functionality broken in HASS 2022.4?

[NickM-27]

🤞 once #242 gets merged, I can redo this and it will be passing, not too sure though with the changes to HA calls

[dermotduffy]

As discussed on discord, try again after rebasing to #243 (and install the new requirements). You may have more luck.

[NickM-27]

Okay just realized my error here being that I can't access the object attributes from the entity state

@dermotduffy should be good for review

[NickM-27]

Cool, that seems to have done it

[dermotduffy]

Thanks @NickM-27 !

I think I would prevent the creation of this update entity in case Frigate is known to be installed via the addon, otherwise there would be two update entities for the same thing, basically (as Supervisor already provides it).
