remote.h: fix space-only indentation in get_remote_group() declaration

[Copilot]

Commit 3e7b9dce27 ("remote: move remote group resolution to remote.c") introduced the get_remote_group() declaration in remote.h using pure-space indentation on its continuation lines, triggering the indent-with-non-tab whitespace check enforced by .gitattributes (*.[ch] whitespace=indent,trail,space,incomplete) and failing the check-whitespace CI job.

Change

• remote.h: Replace all-space indentation on the get_remote_group() parameter continuation lines with proper tab-based alignment (2 tabs + 5 spaces = 21 chars, aligning to the opening (), consistent with the established style across remote.h:

// Before (triggers "indent with spaces" error)
int get_remote_group(const char *key, const char *value,
                     const struct config_context *ctx,
                     void *priv);

// After
int get_remote_group(const char *key, const char *value,
		     const struct config_context *ctx,
		     void *priv);

Running ci/check-whitespace.sh against the corrected tree exits 0.
