Fix check_structure.py NOLINT parsing and an off-by-one report line

Browse Source 
`line.strip("<!-- NOLINT")` followed by `.strip(" -->")` strips any of
the characters in those sets from both ends, not a literal prefix; it
only happened to work for "Examples". A NOLINT'd section name
starting with N, O, L, I or T (e.g. "Notes", "Template parameters",
"Iterator invalidation", "Literals") was silently mangled, so the
suppression did not apply and the checker could report a spurious
missing/misordered section. Parse the comment with a regex instead.
The same fragile strip() pattern was used for heading text; replace it
with a plain prefix slice. Also fix the admonition_title report, which
used the 0-based line index while every other report in the file uses
lineno+1.

Part of #5718
