Add the page title to Segment tracking

[msbt]

We just realized that all docs pages are getting the title "visited_section_docs" in Analytics, because of this line here: https://github.com/crate/crate-docs-theme/blob/master/src/crate/theme/rtd/crate/layout.html#L191

We specifically tell Segment to use that as the page title via analytics.page('visited_section_docs'...

I was playing around with it locally and analytics.page('{{ title }} - {{ docstitle }}', { already seems to give more information, but since this is only a local demo, I don't know if those are the correct tags. Can anyone confirm or suggest better title options?

Cheers, M

thanks to @amotl and #262 this can be closed

@amotl @norosa there is a small problem with pages like https://crate.io/docs/crate/reference/en/4.5/sql/statements/create-table.html - the segment snippet on the rendered page looks like this:
analytics.page('<code class="docutils literal notranslate"><span class="pre">CREATE</span> <span class="pre">TABLE</span></code> - CrateDB: Reference', {

the code to display this is the one above (analytics.page('{{ title }} - {{ docstitle }}', {), any idea how to sanitize this properly to remove the html tags?
