Parsing time in config's `oauth2_expiry_date` failing all glab commands
### Checklist

- Extension version: _1.55.0_
- [x] Operating system and version: _EndeavourOS rolling_
- [x] Gitlab.com or self-managed instance? _gitlab.com_
- [ ] GitLab version (if self-managed) _NA_
(Use the `version` endpoint, like this: gitlab.my-company.com/api/v4/version)
- [x] I have performed `glab auth status` to check for authentication issues
- [x] Run the command in debug mode (like `DEBUG=true glab mr list`) and attach any useful output
### Summary
I was in CET timezone until yesterday, and now I am in IST (GMT+5:30) while travelling. Suddenly, almost all `glab` commands fails with the following error
```sh
ERROR: parsing time "03 Apr 25 21:50 +0530" as "02 Jan 06 15:04 MST": cannot parse "+0530" as "MST"
```
### Environment
- OS: Linux 6.13.7-arch1-1 x86_64
- SHELL: /bin/zsh
- TERM: alacritty
- GLAB: glab 1.54.0 ()
```sh
$cat ~/.config/glab-cli/config.yml

### Steps to reproduce
Probably change your timezone to IST and do something with `glab cli`
### What is the current _bug_ behavior?
Almost all commands fails with `parsing time "03 Apr 25 21:50 +0530" as "02 Jan 06 15:04 MST": cannot parse "+0530" as "MST"`
### What is the expected _correct_ behavior?
No error in the above commands' outputs.
### Relevant logs and/or screenshots
```sh
$DEBUG=true glab auth status
[git remote -v]
[git config --get-regexp ^remote\..*\.glab-resolved$]
gitlab.com
x gitlab.com: failed to initialize api client: parsing time "03 Apr 25 21:50 +0530" as "02 Jan 06 15:04 MST": cannot parse "+0530" as "MST"
✓ Git operations for gitlab.com configured to use ssh protocol.
✓ API calls for gitlab.com are made over https protocol.
✓ REST API Endpoint: https://gitlab.com/api/v4/
✓ GraphQL Endpoint: https://gitlab.com/api/graphql/
✓ Token: **************************
ERROR:

```
```sh
$DEBUG=true glab repo list
[git remote -v]
[git config --get-regexp ^remote\..*\.glab-resolved$]
[git remote -v]
[git config --get-regexp ^remote\..*\.glab-resolved$]
ERROR: parsing time "03 Apr 25 21:50 +0530" as "02 Jan 06 15:04 MST": cannot parse "+0530" as "MST"
```
### Possible fixes
Changing the timezone value in the `oauth2_expiry_date` in glab config, to `MST` gets rid of the issue temporarily.
```diff
- oauth2_expiry_date: 03 Apr 25 21:50 +0530
+ oauth2_expiry_date: 03 Apr 25 21:50 MST
