vim: Bump to 9.1.0888

[Ra2-IFV]

Use release tarballs from Github tags, because mirror sites are still on 9.0.
Refresh patch:

• 002-remove_helptags_generation.patch

Maintainer: @ratkaj but he has not been active for 2 years...
Compile tested: bcm2711 341cc047b9174280d89f1b5494a42837ccbadb12
Run tested: not yet

Description:
Why using tarballs from tags? Because 9.0 was released 2 years ago, and the Vim website itself is distributing 9.1 binary packages...
They also placed a 9.1 tarball at https://www.vim.org/downloads/vim-9.1.tar.bz2 but not the mirror sites.
Ubuntu 24.04 is on 9.1.0496, Debian 12 is on 9.0
9.1 supports XDG standard!

A question: Why do we need this patch 002-remove_helptags_generation.patch

R.I.P Bram Moolenaar you saved me from Visual Studio nightmare... and thanks all Neovim developers

Wait, I didn't fix the hash
Also I want to add basic helps for packages

[Ra2-IFV]

I removed some weird new lines... Not mentioning this the commit message.

I noticed Build/Compile/vim-help is implicit defined in Build/Compile/vim-runtime:
Build/Compile/vim-runtime creates a tar archive that includes files only for vim-help.
I think we have a better practice for this?

[Ra2-IFV]

Also I suggest that we may introduce a breaking change:

Old	New	Description
/	vim	META package for templating
vim	vim-tiny	--with-features=tiny
/	vim-small	--with-features=small
vim-full	vim-normal	--with-features=normal
vim-fuller	vim-big	--with-features=big
/	vim-huge	--with-features=huge

Need discussions.

It might be a good idea to sync vimrc.full with defaults.vim from upstream
