LUDOC-292 fix: Update formatting error in file path

At some point the following line was changed in the
Visualizing Results section of the benchmarking section of
the manual:

/proc/fs/lustre/obdfilter/*/brw_stats

was accidentally changed to:

/proc/fs/lustre/obdfilter/

Also, "*/brw_stats" appeared in a <screen> tag, which was not
the intent.

The patch also updates these 3 paragraph for 80 character max
per line.

- Created a versionbox div class for the div which puts a box around
  version-specific content.
- Created a versioncontent span class for the actual content.
- Put the xsl:apply-templates element inside of a versioncontent span.
- Gave the versioncontent class a margin-left of 15px to move the text
  to the right of the versionlabel.
- Capitalized "Introduced" in the version labels.
