Tag not set correctly using devreleases with semver2 and custom tag_format

[pydal]

Description

When using a custom tag format like ${major}.${minor}-${patch}${devrelease} with semver2 the created tags miss the devrelease part. Further devreleases fail due to duplicate tags.

Steps to reproduce

1. Initialize git project and place cz configuration:

git init .
cat << EOF | tee cz.toml
[tool.commitizen]
name = "cz_conventional_commits"
tag_format = "\${major}.\${minor}-\${patch}\${devrelease}"
version_scheme = "semver2"
version = "0.0.1"
update_changelog_on_bump = true
EOF

2. Create a first commit

echo "# test" | tee README.md
git add README.md cz.toml
git commit -m "fix: Add readme file"

3. Bump a devrelease

cz bump --devrelease 1 --yes

4. Observe incorrect "tag to create" in output tag (note ${devrelease})

bump: version 0.0.1 → 0.0.2-dev.1
tag to create: 0.0-2${devrelease}
increment detected: PATCH

5. Observe inccorect git tag

git tag -l

6. Trying to add more changes and bump the next devrelease will fail

Current behavior

No devrelease part is added according to the configuration. The tag equals ${major}.${minor}-${patch} which produces further errors using a next devrelease.

Desired behavior

The tag shall be set correctly according to custom tag_format and semver2 convention like 0.0-2dev1
