Default options for pyproject.toml

[jhaisley]

It would be better if bump-my-version was able to operate on a default pyproject.toml without a config file.

It already works if [bumpversion] with no options is added to pyproject.toml.

with [bumpversion]
(test-dir) D:\dev\tmp\test-dir [main +0 ~1 -0 !]> uvx bump-my-version show-bump
0.1.1 ── bump ─┬─ major ─ 1.0.0
├─ minor ─ 0.2.0
╰─ patch ─ 0.1.2

without [bumpversion]
(test-dir) D:\dev\tmp\test-dir [main +0 ~1 -0 !]> uvx bump-my-version show-bump

Usage: bump-my-version show-bump [OPTIONS] [VERSION]

Try 'bump-my-version show-bump -h' for help
╭─ Error ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮

Similarly, it also fails if there are only list options added:

[project]
name = "check-sdist"
version = "1.3.1"
...

[[tool.bumpversion.files]]
filename = "README.md"
search = "v{current_version}"
replace = "v{new_version}"

[[tool.bumpversion.files]]
filename = "src/check_sdist/__init__.py"
search = '"{current_version}"'
replace = '"{new_version}"'

Fails (silently) to find anything else to update, while:

[project]
name = "check-sdist"
version = "1.3.1"
...

[tool.bumpversion]

[[tool.bumpversion.files]]
filename = "README.md"
search = "v{current_version}"
replace = "v{new_version}"

[[tool.bumpversion.files]]
filename = "src/check_sdist/__init__.py"
search = '"{current_version}"'
replace = '"{new_version}"'

Works. I don't think TOML is supposed to be able to detect the difference (both make a dict named bumpversion inside tool), so maybe a text string is being looked for somewhere? See henryiii/check-sdist#138.
