Problem

Following #29753 I had a closer look and there are duplicates of several tags

    animation (5)
    component: animation (3)

    component: annotate (2)
    component: annotation (4)

    plot-style: bar (1)
    plot-type: bar (12)

    plot-style: fill_between (1)
    plot-type: fill_between (5)

    plot-style: line (2)
    plot-type: line (38)

    plot-style: polar (1)
    plot-type: polar (5)

    plot-style: scatter (2)
    plot-type: scatter (7)

    plot-type: speciality (3)
    plot-type: specialty (5)

Suggested improvement

I would be good to pick just one for each of these, so the tags are easier to navigate. My suggestions

component: animation follows standard structure
component: annotation could refer to e.g. AnnotationBbox as well as annotate
plot-type: specialty the internet tells me this is the more common spelling (although both are correct), also it's consistent with the section title

plot-type for all the others - plot-style does not appear in the Glossary so I assume those came in by accident.
