Jeff Xu 1834300798 mseal: update mseal.rst 
Pedro Falcato's optimization [1] for checking sealed VMAs, which replaces
the can_modify_mm() function with an in-loop check, necessitates an update
to the mseal.rst documentation to reflect this change.

Furthermore, the document has received offline comments regarding the code
sample and suggestions for sentence clarification to enhance reader
comprehension.

[1] https://lore.kernel.org/linux-mm/20240817-mseal-depessimize-v3-0-d8d2e037df30@gmail.com/

Update doc after in-loop change: mprotect/madvise can have
partially updated and munmap is atomic.

Fix indentation and clarify some sections to improve readability.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
