add deployment strategy option to helm chart (re #3021) (#3155)

@S7evinK sorry for the spam but any chance we get get this merged into
main at some point? It was previously merged in
https://github.com/matrix-org/dendrite/pull/3021 into a temp branch that
never made it into main. If there is an issue with this being merged let
me know.

Minor update to the helm chart to allow setting the update strategy as
the default `RollingUpdate` one is a bit annoying if using
`ReadWriteOnce` volumes for media. Hope this makes sense.
