[http.middlewares] [http.middlewares.rewrite-foo.plugin.rewritebody] lastModified = false
[[http.middlewares.rewrite-foo.plugin.rewritebody.rewrites]]
  regex = 'http://'
  replacement = 'https://'

Try the following configuration.

[http.middlewares]
  [http.middlewares.rewrite-foo.plugin.rewritebody]
    lastModified = false

    [[http.middlewares.rewrite-foo.plugin.rewritebody.rewrites]]
      regex = 'http:\/\/'
      replacement = 'https:\/\/'
