Outdated action versions in validate workflow

[MikeMcC399]

Current behavior

The workflow .github/workflows/validate.yml uses outdated action versions that call on the end-of-life Node.js 12 version:

Action	runs.using
actions/checkout@v2	node12
actions/setup-node@v2	node12
codecov/codecov-action@v1	node12
cycjimmy/semantic-release-action@v2	node12

Node.js 12 entered end-of-life status on Apr 30, 2022.

GitHub Actions currently supports only node20 and node24 for runs.using for JavaScript actions.

Desired behavior

Use only GitHub JavaScript Actions that themselves are using a supported Node.js version (currently node20 and node24).

Suggested resolution

Update:

From	To	runs.using
actions/checkout@v2	actions/checkout@v5	node24
actions/setup-node@v2	actions/setup-node@v4	node20
codecov/codecov-action@v1	codecov/codecov-action@v5	composite
cycjimmy/semantic-release-action@v2	cycjimmy/semantic-release-action@v5	node24
