Fix branch create help message

[jgreet]

I'm not sure why but the backticks change the description of the -cluster-size flag in a confusing way.

On 0.241.0

$ pscale branch create
Error: missing arguments <source-database, branch>

Usage:
  pscale branch create <source-database> <branch> [options] [flags]

Aliases:
  create, b

Flags:
      --cluster-size pscale size cluster list   Cluster size for branches being created from a backup or seeded with data. Use pscale size cluster list to see the valid sizes. (default "PS-10")
      --from string                             Parent branch to create the new branch from. Cannot be used with --restore
...

Can we check other uses of this flag and update their help text too?

[jgreet]

Yeah, taking a look now. There's at least one more in pscale shell

[jgreet]

Actually in shell --help it works. May even be intentional. Same in a few other places

cli/internal/cmd/shell/shell.go

Line 240 in 581cc29

"PlanetScale Database remote network address. By default the remote address is populated automatically from the PlanetScale API. (format: `hostname:port`)")

      --remote-addr hostname:port   PlanetScale Database remote network address. By default the remote address is populated automatically from the PlanetScale API. (format: hostname:port)

But api --help looks wrong, see --method or the two backticks at the end of --field

before:

  -F, --field key=value      HTTP body to send with the request, in key=value format where `value` is a JSON entity, unless `value` starts with a `@` in which case the string after `@` represents a file that will be read. Nested types are represented as `root.depth1.depth2=value``
  -H, --header stringArray   HTTP headers to add to the request
  -h, --help                 help for api
  -I, --input string         HTTP body to send with the request, as a file that will be read and then sent.
  -X, --method --field/-F    HTTP method to use for the request.  Defaults to GET for requests without a body, or POST when a body is specified with --field/-F or `--input/-I` (default "GET")
      --org string           The organization for the current user
  -Q, --query key=value      query to append to the URL path, in key=value format

after:

Flags:
      --branch string        The branch this project is using
      --database string      The database this project is using
  -F, --field stringArray    HTTP body to send with the request, in key=value format where value is a JSON entity, unless value starts with a @ in which case the string after @ represents a file that will be read. Nested types are represented as 'root.depth1.depth2=value'
  -H, --header stringArray   HTTP headers to add to the request
  -h, --help                 help for api
  -I, --input string         HTTP body to send with the request, as a file that will be read and then sent.
  -X, --method string        HTTP method to use for the request.  Defaults to GET for requests without a body, or POST when a body is specified with --field/-F or --input/-I (default "GET")
      --org string           The organization for the current user
  -Q, --query stringArray    query to append to the URL path, in key=value format
