Ensure that the tittle id is unique on the with different subcommand

[ice-tong]

Motivation

I found the URL hash property of the rendered action group tittle could be repeat conflict in one page. The following is a pseudo example to reproduce:

# xxx-cli
Some introduction of `xxx-cli` here...

## xxx-cli subcommand1
Some introduction of `xxx-cli subcommand1` here...
:::{eval-rst}
.. argparse::
   :module: xxx.cli
   :func: get_parser
   :prog: xxx-cli
   :path: subcommand1
:::

## xxx-cli subcommand2
Some introduction of `xxx-cli subcommand2` here...
:::{eval-rst}
.. argparse::
   :module: xxx.cli
   :func: get_parser
   :prog: xxx-cli
   :path: subcommand2
:::
