Fix RST indentation bug in interactive_plots.rst for PR #480

The CI failure in PR #480 was caused by broken indentation in
interactive_plots.rst. The hd.dynspread(...) block was at column 0
instead of being indented with 4 spaces, placing it outside the
RST code-block directive.

When notebooks are generated from this RST file, the unindented code
becomes markdown text instead of Python code, causing notebook
execution to fail.

This commit applies the PR #480 changes (PeptideIdentificationList,
get2DPeakDataLong 5th arg, refactored opts) with correct indentation.
