Fix vscode crash

[inteon]

What this PR does / why we need it:

On VS Code, when running ./hack/update-deps.sh, the git menu crashes because of the large amount of changed files.
VS Code tries to keep track of all file changes, the update script introduces a lot of changes and this causes the crash.
An easy fix is to add the vendor folder to the .gitignore file.

Hi @inteon. Thanks for your PR.

I'm waiting for a jetstack or cert-manager member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Makes sense as a change- do you know at which point the vendor got generated? I see we're removing it here

Interestingly, the vendor folder is created in the update-deps-licenses.sh script that is called by the ./hack/update-deps.sh script. Additionally, it seems like the update-deps-licenses.sh seems to be the slowest step when running the ./hack/update-deps.sh script.

Ahh I see, we do go mod vendor there https://github.com/jetstack/cert-manager/blob/master/hack/update-deps-licenses.sh#L188 .
I guess it downloads and recurses all the deps which might take a long time.
