DAMON user-space tool, damo, has deprecated[1] its old DAMOS schemes
specification format. However, an example of DAMON documentation is still
using it. Update the example to use one of the alternative options.

debugfs
'Getting Started' document of DAMON says DAMON user-space tool, damo[1],
is using DAMON debugfs interface, and therefore it needs to ensure debugfs
is mounted. However, the latest version of the tool is using DAMON sysfs
interface. Moreover, DAMON debugfs interface is going to be deprecated as
announced by commit b18402726bd1 ("Docs/admin-guide/mm/damon/usage:
document DAMON sysfs interface").
This commit therefore update the document to tell readers about DAMON
sysfs interface dependency instead and never mention about debugfs
interface, which will be deprecated.

Information in 'TL; DR' section of 'Getting Started' is duplicated in
other parts of the doc. It is also asking readers to visit the access
pattern visualizations gallery web site to show the results of example
visualization commands, while the users of the commands can use terminal
output.
To make the doc simple, this removes the duplicated 'TL; DR' section and
replaces the visualization example commands with versions using terminal
outputs.

The 'Getting Started' of DAMON is providing a link to DAMON's user
interface document while saying about its user space tool's detailed
usages. This fixes the link.
