feat: update pyproject.toml and __init__.py to automatically get the version number.

[QG-phy]

The version control is achieved by:

1. modify

   format jinja: format-jinja = """
   {%- if distance == 0 -%}
   {{ serialize_pep440(base, stage, revision) }}
   {%- elif revision is not none -%}
   {{ serialize_pep440(base, stage, revision + 1, dev=distance, metadata=[commit]) }}
   {%- else -%}
   {{ serialize_pep440(bump_version(base), stage, revision, dev=distance, metadata=[commit]) }}
   {%- endif -%}
   """

Which have 3 cases: 1. if the commit version is consistent with the tag, then use the tag 2. If the revision (小版本) is not 0, and commit have some history, then new version will be x.x.x+1+devxxxxxxxx. 3. if the revision is 0, them the stage 中版本，will increase by 1 and the dev string will be added.

2. in dptb.init.py:

   import importlib.metadata
   __version__ = importlib.metadata.version("dptb")

   to get the version number
