[PATCH] pull: colorize the hint about setting `pull.rebase`

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

In d18c950a69f (pull: warn if the user didn't say whether to rebase or
to merge, 2020-03-09), a new hint was introduced to encourage users to
make a conscious decision about whether they want their pull to merge or
to rebase by configuring the `pull.rebase` setting.

This warning was clearly intended to advise users, but as pointed out in
https://lore.kernel.org/git/87ima2rdsm.fsf%40evledraar.gmail.com, it
uses `warning()` instead of `advise()`.

One consequence is that the advice is not colorized in the same manner
as other, similar messages. So let's use `advise()` instead.

    pull: colorize the hint about setting pull.rebase
    
    I see that Junio briefly wondered
    [https://lore.kernel.org/git/xmqqeeuecngu.fsf@gitster-ct.c.googlers.com/] 
    about using an advice here, and concluded that it was not needed because
    the warning is self-squelching (i.e. there is already a config setting
    that will silence this warning). But that missed the fact that warnings
    are not colorized, whereas advice is.
