fix: Change 'securityContext/capabilities/drop' from 'all' to 'ALL'.

[boatmisser]

Signed-off-by: Chris Burke christopher.burke@airnz.co.nz

What this PR does / why we need it:
The helm chart default values used the incorrect case for securityContext.capabilities.drop.
Was:

  securityContext:
    capabilities:
      drop:
        - all

Now:

  securityContext:
    capabilities:
      drop:
        - ALL

Fixes #2271

@boatmisser thanks for the PR! Can you run make manifests and push the changes please?

@sozercan
Sorry, my bad, I interpreted that guide as those changes would be "clobbered when we do a new release"; so while I ran make manifests to check the results I did not add them to the commit.

Have now pushed make manifests changes, thanks!
