docs(1password): mark SDK find support in matrix and promote titles (#6568)

The 1Password SDK provider implements dataFrom.find (name regexp on field
labels, tags, and path) in GetAllSecrets, but the support matrix left its
find by name and find by tags cells blank. Mark both as supported, matching
the Connect provider row. Also promote both 1Password provider page titles
from H2 to H1 to match the other provider pages.
