Sometimes when I have an outdated git reference on a branch in my lock file (because of force-pushing on the branch leaving the sha reference invalid), I start getting the following kind of errors:

$ LC_ALL=C bundle
Fetching gem metadata from https://rubygems.org/.......
Fetching https://github.com/decidim/decidim
fatal: Could not parse object 'cb70aded58b9215a495f0509e49daef930eec478'.
Git error: command `git reset --hard cb70aded58b9215a495f0509e49daef930eec478` in directory
/home/deivid/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/bundler/gems/decidim-cb70aded58b9 has failed.
If this error persists you could try removing the cache directory
'/home/deivid/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/cache/bundler/git/decidim-9495d3039168996748af12c0fdb04debdea10392'

I can reliably reproduce this at the moment, but I'm not sure if it's specific to my environment or a consistent reproduction. The steps would be:

git clone https://github.com/podemos-info/decidim-module-votings decidim-votings
git checkout ef92898f56053d631fccaeb4f80bfe7aa4e7359f
LC_ALL=C bundle

Could someone confirm that this is specific to my envirnoment?

There's a related discussion in #6308, but I'm reticketing this to keep the discussion on its own issue!

I can make this give a slightly better error message, but you can (in the meantime) run bundle update decidim --source decidim or bundle update decidim decidim-dev or bundle update --source decidim

#6337 should help give a better error message!

[GitProxy] Fail gracefully when resetting to the given revision fails

### What was the end-user problem that led to this PR?

See #6324 for context.

The problem was when a git gem referenced a branch, and you tried to install on a machine without the revision in the lockfile cached, Bundler would print the following error:

```
Git error: command `git reset --hard cb70aded58b9215a495f0509e49daef930eec478` in directory
/home/deivid/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/bundler/gems/decidim-cb70aded58b9 has failed.
If this error persists you could try removing the cache directory
'/home/deivid/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/cache/bundler/git/decidim-9495d3039168996748af12c0fdb04debdea10392'
```

The problem was that removing the cache directory doesn't help.

### What was your diagnosis of the problem?

My diagnosis was we needed to print a `RevisionNotFound` error when that `git reset --hard` failed.

### What is your fix for the problem, implemented in this PR?

My fix rescues git command failures resulting from that `git reset --hard` and re-raises a more appropriate error message:

```
Revision cb70aded58b9215a495f0509e49daef930eec478 does not exist in the repository https://github.com/decidim/decidim. Maybe you misspelled it?
```

### Why did you choose this fix out of the possible options?

I chose this fix because it didn't involve bubbling information up from the git proxy to the definition. Ideally we'd re-rescue this error somewhere and suggest a `bundle update --source`, but that can be done in a separate PR.
