Description of the change

This is just updates to the README to include a little bit more info on:

• image.flavor (updates table desc, and adds small section below)
• nextcloud.podSecurityContext (updates table desc)
• replicaCount (adds param to table)

Benefits

Easier cross reference between the values.yaml and README.md to save time on getting started :)

Possible drawbacks

I don't really see any drawbacks to updating the readme.

Applicable issues

• fixes replicaCount not mentioned in Readme #310 - adds replicaCount option
• fixes README and values.yaml comments don't list options for image.flavor  #265 - adds better description of fpm and nginx and section explaining how to use it
• fixes doc issue brought up in Add security context for the cronjob, main container, main pod, and ngnix container #269 (comment) - minor copy paste issue

Additional information

This is a change only to the README and does not add additional features, so the Chart.yaml doesn't need a version update.

Checklist

• DCO has been signed off on the commit.
• Chart version bumped in Chart.yaml according to semver.
• (optional) Variables are documented in the README.md

If anyone is curious on future markdown table formatting, in vim I use this plugin: vim-table-mode. Then you can just use the command :TableModeEnable and it will auto-format the markdown table as you change modes in vim.
