fix: rsync example should create db.sql.gz [skip ci]

The Issue

• https://discord.com/channels/664580571770388500/1220763081211121674/1220763081211121674

It was pointed out that if the rsync provider brings down a file as a name other than db.sql.gz, the database gets created with the filename.

This is by design,

ddev/pkg/ddevapp/provider.go

Lines 364 to 374 in 834a772

	if p.DBImportCommand.Command == "" {
	for i, loc := range fileLocation {
	// The database name used will be basename of the file.
	// For example. `db.sql.gz` will go into the database named 'db'
	// xxx.sql will go into database named 'xxx';
	b := path.Base(loc)
	n := strings.Split(b, ".")
	dbName := n[0]
	err = p.app.ImportDB(loc, importPath[i], true, false, dbName)
	}
	} else {

But not useful when the rsync example doesn't explicitly control it.

How This PR Solves The Issue

Change the rsync example to explicitly name the dump file as db.sql.gz

I checked the other examples and integrations and don't find any other example of this ambiguity.

Manual Testing Instructions

Try out this .ddev/providers/rsync.yaml:

environment_variables:
  dburl: rfay@jumphost.thefays.us:~/tmp/xyz.sql.gz

auth_command:
  command: |
    set -eu -o pipefail
    ssh-add -l >/dev/null || ( echo "Please 'ddev auth ssh' before running this command." && exit 1 )

db_pull_command:
  command: |
    # set -x   # You can enable bash debugging output by uncommenting
    set -eu -o pipefail
    rsync -az "${dburl}" /var/www/html/.ddev/.downloads/db.sql.gz
  service: web
