fix reg error in 10-bash.jinjia

[xcfxr]

sed -i use Basic Regular Expression(BRE), so it needs to use Escape character when using character like ')', '?', '+' and so on. I see it may be forgot here. There is another question here. After modifying /etc/default/grub, grub2-mkconfig is not used to make it effective, so the modification is meaningless. Should I directly modify /etc/grub2.cfg (x86) or /etc/grub2-efi/cfg?

Hi @xcfxr. Thanks for your PR.

I'm waiting for a ComplianceAsCode 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.

@xcfxr the PR looks good. Regarding your question, what product are you concerned about?
The macro you modify is then used at line 1955. And it is closely followed by

{{{ grub_command("remove", arg_name) }}}

So this should solve the propagation of the removal to grub.cfg or whatever Grub configuration format is used. Do you agree?
