Add initial Israel sources

I've sent a message to Busofash regarding their error in the GTFS file.

The second one passes locally with the following change and #477:

        {
            "name": "Israel-MOT",
            "type": "transitland-atlas",
            "transitland-atlas-id": "f-sv-גלים~מועצהאזוריתגולן~אפיקים~דןצפון~דןבדרום~דןבארשבע~ירושלים",
            "http-options": {
                "ignore-tls-errors": true,
                "headers": {
                    "user-agent": "Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0"
                }
            },
            "fix": true
        }

Will try your configuration but it seems that Transitland was last updated 5 months ago, not so up-to-date.

[yotamN]

Still not sure why Israel-MOT is closing the connection so I skipped it for now

Although the HTTP RFCs state that the header field names should be case-insensitive, is this always true in practice? I think I've mostly seen "User-Agent" being used.
Maybe it could be worth trying to changing to that?

We might need to make https://github.com/public-transport/transitous/blob/main/src/fetch.py#L60 case-insensitive as well then.
