Parsing of ".python-version" file does not respect comments

[pbrkr]

Steps to Reproduce

1. Run rye init

2. Modify .python-version to start with a comment, e.g.

   # SPDX-License-Identifier: CC0-1.0
   3.12.2

3. Run python3 --version

Expected Result

❯ python3 --version                  
Python 3.12.2

Actual Result

❯ python3 --version
Python version mismatch (found cpython@3.12.2, expected cpython@3.8.18), recreating.

Note that pyenv supports comments in this .python-version: https://github.com/pyenv/pyenv/blob/v2.4.0/libexec/pyenv-version-file-read#L30

  while read -n 1024 -r version _ || [[ $version ]]; do
    if [[ -z "$version" || "$version" == \#* ]]; then
      # Skip empty lines and comments
      continue
    ...
