fix: Fixed escaping in generated configuration files

[hackty]

Description

cause: The renderTemplate function in python.go uses html/template, which HTML-escapes < characters — turning <0.10.0 into <0.10.0 in the generated pyproject.toml.

fix: Fixed escaping in generated configuration files by switching from html/template to text/template

before

[project]
name = "xx-tool-dify-plugin"
version = "0.0.1"
requires-python = ">=3.11"
dependencies = [
    "dify-plugin>=0.9.0,<0.10.0",
]

and after

[project]
name = "xx-tool-dify-plugin"
version = "0.0.1"
requires-python = ">=3.11"
dependencies = [
    "dify-plugin>=0.9.0,<0.10.0",
]
