fix: NumberedPager._render_keyboard

[MarsMinerstone]

The number of buttons was limited by the telegram limit and only 8 were displayed. Added a transfer to the next list to create several rows with buttons

Before:

After:

This can be easily achieved wrapping pager with Group()

Anyway, probably it is a good default behavior

[MarsMinerstone]

can not figure out how to to make it using Group:

def verses_window() -> Window:
    LeaveComment = leave_comment(message_from=MessageFromEnum.Bible_Verses_window)
    return Window(
        MediaScroll(
            media=DynamicMedia("item"), items="photos", id="m_photo", when="photos"
        ),
        NumberedPager(scroll="m_photo"),
        state=MainSG.BibleVerses,
        getter=photos_getter,
    )

[Tishka17]

Window(
    MediaScroll(
        media=DynamicMedia("item"), items="photos", id="m_photo", when="photos"
    ),
    Group(
         NumberedPager(scroll="m_photo"),
         width=6,
    ),
    state=MainSG.BibleVerses,
    getter=photos_getter,
)
